As the University of Wisconsin-Madison celebrates the “Year of the Wisconsin Idea,” recognizing a century of contributions to the greater public good, it’s worth reflecting on how

ingrained that tradition has become in engineering.The Wisconsin Idea drives us to extend the benefits of UW-Madison

work to the citizens of the state and beyond. We see its expansive influence on areas such as healthcare, with new treatments, tools and services that improve quality of life. We also see it reflected in economic impact, through hundreds of spinoff companies and tens of thousands of talented, uniquely trained graduates making their mark on the world.

Here’s another perspective. This year, the Wisconsin Idea has come alive in the College of Engineering through unprecedented outreach to the next generation. As we detail in our 2011 Annual Report, this has been a transformative year in exposing young people to the possibilities of a career in science and engineering.

Why does this outreach matter? Because it’s at the top of the list of concerns of America’s largest employers, who require a greater infusion of talent in science, technology, engineering and math (STEM) in order to stay globally competitive. They need universities to help address a mismatch between current workforce skills and the skills required for new and emerging jobs. And they need a workforce that better represents the ethnic, cultural and gender diversity of the nation at large.

In 2011, we took this pursuit further than ever before. The center-piece was hosting the 2011 National Science Olympiad competition in May. More than 6,000 competitors, parents, educators and volunteers converged on campus for four days of fun and spirited competition.

Our visitors saw UW-Madison at its finest, with homerooms in our new Union South, a daylong showcase in the Wisconsin Institutes for Discovery, competitions across engineering buildings and ceremonies in the Kohl Center. For most of these young people, their first exposure to Wisconsin will stay with them forever.

We are also making greater strides in reaching middle-schoolers, whose academic pathways are starting to solidify. The highly successful “Camp Badger” took its show on the road this summer. With support from 3M Corporation, a camp at UW-River Falls gave two-dozen north-western Wisconsin kids a weeklong exposure to engineering. And our middle-school modules, which introduce young people to engineering “grand challenges,” debuted in six Wisconsin middle schools this fall.

Our diversity outreach programs have produced groundbreaking success. The Engineering Summer Program (see story on back cover), now entering its 40th year, has a nearly 100-percent success rate in preparing high school students for undergraduate enrollment—including more than 70 percent who pursue engineering. And our cover story on the Graduate Engineering Research Scholars (GERS) program highlights a decade of tremendous progress, as GERS produced 46 master’s and 45 PhD recipients from underrepresented backgrounds since 2000.

And, as always, our undergraduates put on quite a show during Engineering EXPO in spring 2011. More than 7,000 visitors—including 114 busloads of K-12 students —enjoyed the 45 interactive exhibits scattered across the college.

As engineers, the impulse to share our successes and prepare the next generation starts early and stays with us throughout our careers. This is our Wisconsin Idea.

=A decade of gains in graduate student diversity

By Renee Meiller

Throughout the past decade, UW-Madison has earned myriad accolades for everything from its status as a global powerhouse for research and education to its efforts in sustainability and its ability to produce corporate CEOs.

On the College of Engineering campus, there’s a more subtle— yet no less meaningful—success story playing out.

4

The answer—recruit and retain more minority graduate students—was obvious. Yet the process for achieving that goal is an ongoing effort.

In the College of Engineering, GERS originated based loosely on a model developed by Richard Tapia, an engineering professor at Rice University. At UW-Madison, its aims are to build the campus community of minority graduate students in engineering and to provide a pathway for those students to attain top positions in industry, government and academia. For the latter, a major GERS objective is to produce more faculty of color and create systemic change in overall diversity in engineering.

In 1999, the college hired Kelly Burton as GERS coordinator and she and Henderson began recruiting students into the program in 2000. Each year, the two attend the national conferences of such organizations as the National Society of Black Engineers, Society of Hispanic Professional Engineers, American Indian Science and Engineering Society, and the National Science Foundation-funded Louis Stokes Alliances for Minority Participation Program, among others.

Additionally, Burton coordinates the two major GERS recruiting efforts: Opportunities in Engineering, an annual weeklong conference that draws undergrad juniors and seniors to campus to explore graduate education in engineering; and SURE-REU, a nine-week summer under-grad research experience supported by the college, the UW-Madison Graduate School, and the NSF-funded UW-Madison Materials Research Science and Engineering Center. The program enables undergraduates to conduct laboratory research in engineering, meet current engineering graduate students, develop a network of supportive peers in GERS, and learn about the graduate application process and outside fellowships. Now, approximately 50 students annually participate in GERS.

It’s the story of the Graduate Engineering Research Scholars, or GERS, a program that since 1999 has increased opportunities for talented minority graduate students to study with world-class UW-Madison engineering faculty and achieve their goals for higher education in science, technology, engineering and math. In January 2011, the program received national attention when U.S. President Barack Obama presented Douglass Henderson, a professor of engineering physics who directs the program, the Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring.

Since 2000, 45 students in GERS have earned PhD degrees through the College of Engineering. In comparison, fewer than 350 minority students have earned PhDs nationwide in the past decade, according to the American Society for Engineering Education 2009 edition of Engineering by the Numbers.

When GERS began, the graduate student profile of the College of Engineering looked much different, says Henderson. “We had about nine to 11 minority graduate students in the college, with an enrollment of about 1,200 graduate students,” he says. “Among the faculty, we were hearing that there weren’t many minority students to draw from, and one of the obvious questions was why. We’re doing top-rated research, and we’re one of the top-ranked research universities.”

GERS scholar Arrielle Opotowsky

Strong personal connectionsIn 2006, Arrielle Opotowsky was an undergraduate at Louisiana State

University, pursuing bachelor’s degrees in physics and astronomy. She spent the summer in Madison participating in the SURE-REU Program. During that summer program, Erwin W. Mueller Professor and Bascom Professor of Surface Science in Materials Science and Engineering Max Lagally was Opotowsky’s advisor. Now, Opotowsky is a GERS scholar pursuing a PhD under Lagally through the Materials Science Program. “I knew he was the best option I could ever hope for in terms of an advisor,” she says, of her decision to attend graduate school at UW-Madison. “And I knew that GERS would be a great support group if I chose to come here.”

That personal connection—which often begins before GERS scholars ever visit the UW-Madison campus—is key to recruiting and retaining the students. “The friends I’ve met through GERS mean a lot to me, given that my whole social network in Madison stems from GERS scholars,” says Shannon Roberts, an industrial and systems engineering PhD student investigating the role of feedback in changing driver behavior under Industrial and Systems Engineering Professor John Lee.

Henderson and Burton recruited Roberts at a National Society of Black Engineers national conference in 2009 and a special GERS welcome weekend. “When I first moved here, GERS scholars were the first to invite me to events and help me navigate campus,” says Roberts. “Without them, I’m sure I wouldn’t be as far along as I am, both in terms of my social life and my academic progress.”

Nationally recognized scholarsGiven the university’s rigorous standards,

academic progress is of the utmost importance, and GERS participants are top-notch scholars. However, an outstanding academic track record doesn’t automatically guarantee success in graduate school. So, before GERS students set foot on campus, Henderson and Burton work with engineering faculty to ensure the students’ research interests and academic goals are a good fit. The two work with faculty to help secure financial support, including fellowships and research assistantships, for incoming GERS scholars.

Currently, 10 GERS scholars—including Opotowsky and Roberts— also hold National Science Foundation Graduate Fellowships. This prestigious award program recognizes outstanding graduate students and provides them three years of support, a $30,000 annual stipend, a $10,500 cost-of-education allowance, access to a powerful super-computer, and international research and professional development opportunities. “The NSF fellowship not only provides funding for three years of my studies, but provides me with freedom to work on projects I am interested in,” says Ricardo Alamillo, a chemical and biological systems engineering PhD student and GERS scholar working on using heterogeneous catalysis to convert biomass to chemicals and fuels

under Steenbock Professor of Chemical and Biological Engineering James Dumesic.

Tam Mayeshiba, a GERS scholar who is studying ways to make more cost-effective solid oxide fuel cells under Materials Science and Engineering Associate Professor Dane Morgan, says the NSF fellowship keeps her grounded in responsibility. “I want to do work worthy of being an NSF fellow,” she says. “I also like being part of a national program that values research in all kinds of different areas.”

She says she feels her participation in GERS strengthened her NSF application because of the GERS focus on increasing the diversity of science, technology, engineering and math fields. “I was also motivated by the idea that I could help the GERS program by securing a fellowship, both because it would be an additional credit to the program and because I could free up funds for other students,” says Mayeshiba, whose career plans include becoming a professor.

In the past two years, 10 of 20 College of Engineering students who received the NSF fellowship were GERS students. That high percentage is a testament to the commitment GERS scholars have made to help

each other succeed. Roberts is a 2010 NSF fellow-

ship recipient and since has provided advice to her fellow GERS scholars. “As the reviewers read literally hundreds of essays a day, it’s important that students’ application really stand out from the rest,” she says. “I think it’s important to mentor students during this process because I had a lot of help when I was applying for fellowships and I want to give that same help to other students.”

When NSF announces the fellowships each spring, Roberts is first to notify GERS. “I think she is as excited as the new recipients,” says Burton. “We celebrate with a cake, complete with the NSF logo, at the next GERS meeting.”

An inclusive, supportive campus cultureGERS also provides a network of moral support and attempts to

alleviate the isolation many minority students often feel on campus. The program offers biweekly meetings GERS scholars are required to attend. They help plan the meetings and play active roles on committees ranging in focus from social to recruiting. “It’s professional development, but we spend a little bit of time just being in the same room together,” says Burton. “They don’t otherwise see each other.”

But even that’s changing, as the college and UW-Madison continue to invest in efforts that increase the number of minority students—both at the undergraduate and graduate student levels—on campus. Offshoots of the GERS program now exist in seven other schools, colleges

6

or programs at UW-Madison and the climate on campus for diverse students is improving. “We see the culture change,” says Henderson. “The faculty say they see a lot more minority graduate students in the College of Engineering. They see students in the classrooms and performing well—or better than they had perceived or thought before. We see faculty picking up more minority students for research. Now they see other students’ successes and know the GERS program is bringing strong students—and the NSF fellowships reinforce that we’re getting very good students.”

Perhaps the strongest testament to the quality of the GERS scholars is number of graduates who have advanced into high-level science, technology, engineering and math jobs. It’s an area currently lagging in diversity, says Henderson. “We hope there’s a pyramid effect here, that more students will filter in, graduate and get hired into faculty positions,

Rube Goldberg competition

industry and research positions,” he says. “And by increasing the number of people in these positions, hopefully they’ll move up.”

In a decade, nine of 45 GERS PhD graduates have taken full-time, tenure-track faculty positions, eight are postdoctoral students, three are pursuing or have earned MD/PhD degrees, seven work at a national lab, and the remaining GERS graduates have found jobs in industry.

Many of those former students keep in touch with Burton via Facebook and E-mail, and they often drop her notes to share high points in their lives and careers.

That connection is among the many reasons Burton is dedicated to keeping GERS going strong. “I’ve always wanted everybody to have equal opportunity to be who they could be,” she says of the scholars. “That’s what motivates me every day. It’s a gift to watch all of them go out and succeed.”

to experience hands-on engineering activities and to explore five build-ings on the engineering campus. EXPO included six competitions and featured more than 45 hands-on exhibits and demonstrations. First-graders from Sauk Prairie schools toured the fusion experiment Pegasus. Third-graders from Leopold Elementary School in Madison learned how materials behave under extreme conditions as they watched materials science and engineering students use liquid nitrogen to freeze a banana and use it as a hammer. Eighth-graders from Savannah Oaks Middle School, Verona, learned how municipal solid waste facilities work at an exhibit titled, “What happens to your garbage?” For the Rube Goldberg competition, teams of high school students designed and built a complex machine that could raise a flag in 20 or more steps.

Leopold parent Kris Cotharn appreciated EXPO’s emphasis on exploring current scientific achievements to encourage future scientific endeavors. “I think it’s important to expose them to opportunities they have if they go into the field of science,” she said.

Standing anywhere in the Engineering Centers Building atrium April 14, 15 and 16, it was impossible to ignore the bass thundering out

of a very large stereo speaker located at the north end of the building.This was no ordinary speaker.“Just last night,” said electrical engineering PhD student Dan Ludois

on April 14, “we submitted it to the Guinness Book of World Records.” Measuring 8 feet square and 2 feet deep with a 6-foot-diameter

cone, the speaker truly was one of a kind. Ludois and friends Justin Reed and Kyle Hanson built it specifically for its attention-grabbing value at Engineering EXPO, a biennial three-day event that draws thousands of students, teachers and parents to the College of Engineering campus.

The group succeeded. The super-sized speaker—and Engineering EXPO itself—attracted nearly 7,000 elementary-, middle- and high-school students, teachers and parents from such Wisconsin locales as La Crosse, Whitewater, Poynette and Sheboygan Falls. “We had 74 buses of students show up on Thursday and 40 on Friday,” says Alicia Jackson, who directs the Student Leadership Center in the College of Engineering.

In a two-year process that begins not long after the last event ends, EXPO is planned and staffed entirely by engineering students. This large-scale open house offers students from all engineering disciplines the opportunity to share their passion for engineering with public audiences.

For South Carolina students, a nuclear engineering degree is within reach

More than 6,000 middle- and high-school students, educators and parents from 47 U.S. states visited UW-Madison May 18-21, 2011, for the 27th annual National Science Olympiad tournament. An after-school team activity, Science

Olympiad is one of the nation’s most prestigious and rigorous competitions of science, technology, engineering and math (STEM). At both the state and national level, teams compete in more than two-dozen scientific and engineering challenges on topics ranging from human health, ecology, chemistry, cell biology, geology and engineering.

American competitiveness hinges on increasing the number of people educated in STEM—and U.S. Department of Labor statistics indicate demand for workers with expertise in these fields is rising. The Science Olympiad focus on teamwork, cooperation and real-world challenges can be a powerful tool in promoting interest in such disciplines.

UW-Madison landed the 2011 competition thanks in large part to College of Engineering Dean Paul S. Peercy. In 2005, Peercy developed an outreach program through which engineering undergraduates serve as mentors to help area schools form teams. More than two-dozen NSO teams have been established through the effort, bringing the Wisconsin team total to more than 100. “Increasing the number of people educated in science, technology, engineering and math fields is vital to American competitiveness,” says Peercy. “Science Olympiad is one of the best programs I have encountered for inspiring a lasting interest in STEM disciplines.”

View videos about the 2011 national tournament on the Science Olympiad playlist at youtube.com/engineeringuw.

A record number of South Carolina State University (SCSU) students attended nuclear engineering courses on the

UW-Madison campus in spring 2011. These nine students will earn degrees from both the SCSU Department of Civil and Mechanical Engineering Technology and in nuclear engineering and from the UW-Madison Department of Engineering Physics.

The program began at UW-Madison in 2001 under Engineering Physics Professor Emeritus and then-Chair Gil Emmert. The unique collaborative educational opportunity is the result of the Department of Energy Nuclear Engineering University Partnership Program. Designed to increase the

number of minorities entering nuclear engineering, the program pairs students from minority-serving colleges and universities with institutions that offer a nuclear engineering degree.

“Here in Madison, the students have access to our reactor lab, which SCSU does not have,” says current EP Chair Jake Blanchard. “Students take a heavy load while they’re here, including courses in reactor operations, theory and design; economics and the environment; and our senior design class.”

Like UW-Madison students, the SCSU students graduate pre-pared to work in any part of the nuclear industry, from planning to designing, developing, testing and operating nuclear reactors. Because the SCSU curriculum emphasizes the fundamentals of engineering, students also are prepared for graduate studies in such fields as radiological sciences or materials science.

If a UW-Madison faculty member is late to work, it’s likely due to traffic. When Diana Morris, dean of instruction at the College of Menominee Nation (CMN), was late one morning, it was because a

bear was sitting on her car.CMN is located at the southern end of Keshena, Wisconsin, a town

of about 1,200 bordered by the expansive Menominee Forest. Founded in 1993 in the president’s basement with 43 students, CMN has grown into an established two-year college that includes campuses in Keshena and Green Bay and offers more than 20 majors and certificate programs to almost 700 students.

Around 80 percent of CMN students are American Indian and represent tribal communities across the country. Most are first-generation female students, and for many, the only people with college degrees they interact with regularly are doctors and teachers. Most, even those who are traditional-age college students, have at least one child.

“Many of our students don’t even know what an engineer is,” Morris says. Yet Morris and her collaborators at UW-Madison and UW-Platteville want to do much more than tell CMN students the job exists—they want to help these students actually become engineers.

The three schools are working together as part of a National Science Foundation-funded initiative to increase the number of American Indian students who transfer from CMN to UW-Madison and UW-Platteville to study engineering. The collaboration team aims for 10 students to

transfer in the next five years.While the goal may seem modest, that number

would more than double the current number of students who transfer to UW-Madison

from CMN to pursue any field.

From the Menominee Forest to Madison: Engineering a path for American Indian transfer students

By Sandra Knisely

There are fewer than 30 American Indian students in the College of Engineering, of around 250 American Indian students enrolled at UW-Madison as of fall 2010.

UW-Madison has long recognized the importance of increasing participation of underrepresented minorities in science, technology, engineering and math (STEM) fields, and the partnership with CMN is yet another opportunity to do so, says Manuela Romero, assistant dean for student diversity and academic services in the College of Engineering.

“Nationally, minority students are most likely to begin their academic careers at two-year campuses,” Romero says. “This is true for Native students, and if we’re going to increase participation of under-represented students, we have to look at two-year campuses.”

Establishing a strong foundationFor the last few years, CMN has worked on expanding its programs

and developing pre-engineering and materials science courses under various other national grants.

Romero had a relationship with CMN during her tenure as the director of the Wisconsin Alliance for Minority Participation. When Romero joined the College of Engineering in 2009, Morris quickly got in touch to collaborate on the proposal that was eventually funded by an $825,000 grant from the National Science Foundation Tribal Colleges and Universities Program and the NSF Directorate for Engineering.

CMN also partnered with UW-Platteville, which has many first-generation college students and is located in a community much smaller than Madison.

significant financial and time-management adjustment. YoungBear-Tibbetts balances homework with a full-time position at the Great Lakes Indian Fish and Wildlife Commission, a part-time job as a science outreach coordinator at the UW Arboretum Earth Partnership for Schools and, most importantly, her 6-year-old twin boys.

“I’ve been at the point where I’ve said this is not worth it. I can’t do this. I’m leaving,” she says. “I’ve felt that. I’ve been there.”

YoungBear-Tibbetts credits her relationships with several American Indian faculty members at UW-Madison as the reason she has stayed and been successful. “When I had a problem, there was no question who I would go to. My drive was having those mentors,” she says. “You learn from a mentor, then you start mentoring other people. That’s how we do things.”

Strong relationships on campus will be important for all students who transfer from CMN, says Morris. “This is true for every student, but it is core to the success of Indian students,” she says. “The ability to build a relationship with someone on campus can be the make or break.”

The UW schools each will have advisors who work at both CMN and their respective UW institution, so students can get to know those advisors during their time at CMN and continue the relationship once they have transferred.

Strengthening the futureDespite the challenges individual students may face during the

transfer process, increasing the number of American Indian engineers will have many economic and community benefits in northern Wisconsin and elsewhere.

In the Northwoods region of the state, American Indian tribes are among the largest employers, with most working for tribal governments or casinos. “But the tribes need to diversify,” Morris says. “They’re looking for workforce opportunities.”

As CMN grows, so too will the number of science-related jobs it can offer. Morris hopes students who transfer from CMN to UW schools eventually will hold some of these jobs. CMN is the first and only tribal college in the United States to host a U.S. Forest Service research station, and Morris anticipates it will create around 60 jobs. Additionally, CMN plans to establish a materials science program that will emphasize fiber and wood products and hire several engineers and scientists.

Beyond economic development, there are additional benefits to establishing a new engineering workforce in tribal communities. “Indian students say they are getting their degrees for two reasons,” says Morris. “One is to return to the community and serve in whatever way will bring the community forward. The second is to serve as a role model for the young ones, to demonstrate that this is a career Indians are engaged in.”

For YoungBear-Tibbetts, there’s no question what motivates her as a student at UW-Madison and coordinator at the Arboretum. “Most Native people have this theory that seven generations—which are either the next seven generations or the past three, present and next three generations—all have to be considered when we make any decision,” she says. “I’m not doing this for me. I’m doing what I’m doing for the kids.”

The engineering disciplines that typically are of most interest to American Indian students are civil, environmental and mechanical engineering. Faculty members from these departments at both UW schools are participating in a working group that began meeting in spring 2011. The group will help CMN develop a more extensive science and math curriculum and establish a clear path for students to transfer to either UW institution.

The collaboration team also will look at building a STEM foundation for American Indian students long before college. The grant will support an outreach coordinator to visit K-12 tribal schools in Wisconsin and perform experiments with students and give advice about how to prepare for college and a STEM major in particular.

“The intent of the grant is to make sure CMN can provide a strong foundation for their students so they can go on and transfer,” Romero says. “We’re not going to see all the fruits of this labor by the end of the five-year grant. We will see the real benefits later, once CMN has the structure in place to provide students with strong skills so their students will be successful here.”

Fawn YoungBear-Tibbetts is one of the students who has made the transfer from CMN to UW-Madison. She is majoring in life sciences communication in the College of Agricultural and Life Sciences (CALS). Though she transferred with three other students who all enrolled in CALS, YoungBear-Tibbetts is the only one of the group who didn’t switch to different program because of challenges with the math requirements.

Relying on relationshipsExposure to STEM and access to introductory coursework aren’t the

only issues that prevent many American Indian students from pursuing an engineering degree. Many CMN students also juggle childcare and significant financial concerns. “Finding pizza money on a Friday night is the least of their worries,” says Morris.

Growing up, YoungBear-Tibbetts knew several scientists and her mother earned a geography degree from UW-Madison in the 1980s. “I practically grew up in Science Hall,” she says.

Despite the early exposure to higher education, YoungBear-Tibbetts didn’t immediately pursue a degree after graduating from high school. Instead, she moved to Minneapolis to paint murals and work for a cultural outreach program for several years.

She eventually returned to Wisconsin, and after earning her associate’s degree at CMN, YoungBear-Tibbetts decided to follow in her mother’s footsteps and continue for a bachelor’s degree at UW-Madison.

Though YoungBear-Tibbetts was more prepared than most for the culture shock of moving from CMN to UW-Madison, she still faced a

Showing middle school students the societal side of engineering

By Sandra Knisely

“This project exemplifies the Wisconsin Idea,” Cramer says. “It is our hope these students will see engineering in a whole new light.”

Engineering grand challenges The National Academy of Engineering has laid out a set of major

societal issues that will require innovative engineering solutions in the 21st century. The challenges are broad-sweeping and include energy, healthcare and urban infrastructure, among several others.

The Grand Challenges for Engineering initiative first came to UW-Madison in the form of an introductory engineering course spearheaded by Hagness and introduced in 2008. The course, which is now open to students across the UW-Madison campus, is based on a set of modules that asks students to investigate the various political, environmental, ethical and legal constraints behind technical solutions.

The middle school program is an extension of the philosophy behind that course, which targets first-year college students because studies indicate early exposure to the societal impact of engineering helps retain students in the field.

With the new program, UW-Madison engineers are reaching out even earlier in the education pipeline. “Middle school is the time when students start having to make choices about what courses they’ll take in high school,” Wendt says. “This gives us the opportunity to expose them to the humanitarian applications of engineering before they’ve ruled out engineering without really knowing what it is.”

When Electrical and Computer Engineering Professor Amy Wendt (right) was in ninth grade, her teacher asked the class if anyone liked math. Sitting in the front row,

Wendt eagerly put up her hand. Then she realized she was the only one. Now, Wendt is helping math and science teachers ask their students

a different question to get them thinking about careers in engineering: Would you like to help society?

Led by Wendt, a UW-Madison team is working closely with teachers, counselors and administrators at six Wisconsin middle schools to develop a new kind of engineering outreach program.

Along with Wendt, the UW-Madison team consists of Philip Dunham Reed Professor of Electrical and Computer Engineering Professor Susan Hagness (left) and College of Engineering Associate Dean of Academic Affairs Steven Cramer, along with School of Education Professor L. Allen Phelps and Assistant Professor Kimberly Howard. Several graduate students are involved, including Lauren Aneskavich, Kevin Cheng and Tam Mayeshiba from the College of Engineering and Jacob Diestelmann, Stephen Gresham and Tsu-Lun Huang from the School of Education. Edgewood College Professor Amy Schiebel also contributes.

The current list of schools the team will work with includes Lodi Area Middle School, Madison Middle School and Kaleidoscope Academy/Roosevelt Middle School in Appleton, Mitchell Middle School and Starbuck Middle School in Racine, and Westfield Area Middle School. The schools represent a mix of urban and rural schools from different areas of the state close enough for the UW-Madison researchers to visit regularly.

During the 2012-2013 school year, the team will introduce two more modules that will address clean water and biomedical challenges.

Each module will include classroom activities ranging from pencil and paper assignments to design and testing projects to watching videos about UW-Madison alumni working in the field.

“One of our goals is to have a curriculum that goes beyond the scientific method, where you form a hypothesis and test it,” Wendt says. “We’ll look more at how to achieve an engineering goal when you have constraints, so students can get a flavor of the engineering design process.”

Eager for some companyWhile the program aims to reach out to a broad range of students,

inspiring female and underrepresented minority students is a particular goal for Wendt and Hagness.

Wendt says there were few women in many science-related careers when she became an engineer. Yet as the decades went by and other fields, such as medicine and the life sciences, saw substantial growth in terms of female practitioners, the number of women in engineering remained stalled. Women on average make up 18 to 20 percent of the engineering undergraduate student population at UW-Madison.

“I’m eager to have more company,” Wendt says. “It seems like a shame to me that girls are missing out on some really exciting opportunities just because they aren’t aware those opportunities exist at the time they start to think about careers.”

Though they know not every student, female or male, will go into engineering after participating in the UW-Madison program, Wendt and Hagness say overall it’s a great opportunity to raise the profile of the profession.

“We can inform the students, who will become the general public, and give them a better appreciation for engineering,” Hagness says.

The UW-Madison researchers hosted a weeklong workshop in summer 2011 for middle school teachers in the program.

There are additional social issues in middle school that make it an ideal time for outreach. “Middle school is a very impressionable time for students,” Hagness says. “It’s the first time in a student’s academic career when peer influences really start to affect choices.”

Those influences can spread misconceptions about engineers, such as the stereotype that a student has to be a math whiz or will spend their career in a cubicle building gadgets.

The UW-Madison researchers will emphasize instead that engineering can be a powerful gateway to helping society. “At a basic level, I hope to just influence the awareness and attitude of students that some things aren’t just a social issue or technical issue but are a mix of factors,” Wendt says.

Everybody’s doing itThe program will include four classroom modules, each of which will

provide up to three weeks of flexible instructional content that science and math teachers can draw from and fit into their lesson plans.

The UW-Madison program is different from other outreach programs because it incorporates the modules directly into regular math and science courses instead of establishing elective courses or extracurricular activities. Every student at the participating schools will be exposed to engineering, rather than only those who self-select to join voluntary outreach programs.

“Doing this in core classes means everybody’s doing it, and if it’s a positive experience for everybody, then a student who’s kind of excited about it won’t feel as much of an oddball,” Wendt says.

The program has received a three-year grant of nearly $1 million from the National Science Foundation, as well as additional support from the Plexus Foundation, Young Scientists of America and the Carl Marschke family. The funds cover module materials, questionnaires to examine students’ impressions before and after each module, a summer workshop for teachers at UW-Madison and travel costs to allow teachers and researchers to frequently meet over the next two years.

Two of the modules will be introduced in the partner schools during the 2011-2012 school year and will present particular themes as multidisciplinary problems. In the solar energy module, for example, students will look at solar cookers, solar water heaters and photovoltaic lights.

The restoring infrastructure module will go well beyond building toothpick bridges. Students will learn about the broad challenges involved in restoring bridges across the country, including materials science questions and how electrical sensors can monitor bridges. Students also will learn how engineers retrofit buildings and structures to mitigate damage from earthquakes and hurricanes.

scaffolding around damaged tissue. It acts as a kind of gel that mimics the extracellular matrix of tissue, which helps cells interact and tissue regenerate. “This helps maintain moisture and allows for very intimate contact with tissue to speed up the regeneration process,” Kao says.

“The material can be used along with drug therapies.”

Today a small army of professional experts, from inside and outside academia, is bringing the technology to fruition. Kao’s team includes two private contract labs and three contract manufacturers; surgeons at UW Health; other partner hospitals; and experts on intellectual property, Food and Drug

Administration regulations and startup company management.Interested parties will now get a patent with the proof of concept;

the manufacturing know-how and the clinical benefits are already built in.

What also should be attractive is the tremendous need for better alternatives in chronic wound healing. Chronic wounds affect nearly six million patients per year, with healthcare costs estimated at $20 billion. This technology could impact burn patients, people who suffered severe physical trauma such as a car accident, and people who have complications from conditions such as diabetes.

With sensors that are placed directly on the dura mater, the tough coating between the skull and brain tissue, Williams’ advance represents a “tradeoff of risk and reward.” His approach has led to improved measurement of key brain activity while staying outside the blood-brain barrier to avoid complications of infection. The sensors work by monitoring the part of the brain responsible for a particular action—in stroke patients, for example, arm or leg movement. “We coordinate the brain’s intent to move your arm with the actual movement, with the goal of facilitating faster recovery,” Williams says.

This is a high-technology twist on traditional stroke therapies, which work to retrain the brain to control specific movements. But with technology, there is a precise connection between cause and effect. “The way the brain rewires is it looks for coincidences,” Williams says. “That’s the fundamental basis of learning and brain plasticity: the idea that ‘neurons that fire together, wire together.’”

Supported by both the National Institutes of Health and the Coulter Foundation for Translational Research, Williams has clinical trials underway with colleagues at UW Health. The epilepsy team includes Neurological Surgery Assistant Professors David Niemann and Karl Sillay. The stroke project includes Radiology Assistant Professor Vivek Prabhakaran and Neurology Assistant Professor Justin Sattin.

With careful thought, brain sensors connect neurons with actions

Neurologists who work to unlock the secrets of brain activity encounter what one might call the Las Vegas

effect: “What happens in the brain, stays in the brain.”The skull and dura mater are efficient insulators,

keeping high-frequency electrical activity from leaving the brain. And between the blood-brain barrier and the brain’s aggressive immune system, nothing enters the brain without a fight—essential for staving off disease, but tough for medical interventions.

This is the challenge for Associate Professor Justin Williams. He and his students develop sensor technologies that capture stronger and more medically valuable signals from the brain, for use in therapies for stroke and epilepsy patients. This computer-directed therapy could be beneficial for millions of people who are living with epilepsy or the effects of chronic stroke. Williams says it is especially promising for patients who have reached a plateau in traditional therapies.

From patent to proven product: A new approach to tech transfer

On paper, it’s listed as U.S. Patent No. 7,615,593: “A faster and more effective way to treat chronic wounds through the use

of a liquid cellular matrix, rather than conventional bandages.”But in practice, the patent is the subject of an exciting shift in thinking

at UW-Madison about how to move medical technology from patent to product.

Developed by Professor John Kao (also pharmacy), the technology is one of the first tests of a new “de-risking” strategy developed in partnership with the Wisconsin Alumni Research Foundation. This project will take the technology full-circle, from a theoretical patent to a prototype product that is validated in human clinical trials. “This is a completely new way of thinking from an academic perspective,” says Kao. “We’re not just developing a patent. We’re looking at licensing a proven product.”

Kao first developed his wound-healing technology in 2002, and immediately saw its advantages over current treatments for burns and traumatic injuries. The process of applying, removing and reapplying gauzes is painful, costly and offers little enhancement of the healing process.

recommends using MRI as the top surveillance tool for high-risk breast cancer patients, which includes an estimated 1.4 million American women.

The “blind” approach to MRI-assisted biopsies means that even the slightest movement of the patient or the tissue can shift the target and lead to a failed biopsy, causing additional painful readjustments or return visits.

The new technology tackles two challenges. First, current MRI scanner design makes it nearly impossible for interventional access to the patient during imaging. Block’s research team developed a different kind of MR breast coil that leaves open a variety of angles accessible to a biopsy needle.

The second challenge is in designing a functional device within MRI’s high magnetic field environment. For this, the team is partnering with Mechanical Engineering Assistant Professor Michael Zinn, who is building a robotic arm that would control the needle with piezoelectric motors.

Other collaborators include (from left, next to Block) Radiology Assistant Professor Roberta Strigel, Medical Physics Researcher Ethan Brodsky, Radiology Associate Professor Frederick Kelcz, and Marvel Medtech CEO Ray Harter.

In the world of medical imaging, no single technology provides all the answers for the critical procedure of breast cancer biopsy.

Magnetic resonance imaging (MRI), for example, produces clear, highly revealing images of potential breast cancer lesions, but lacks practicality in obtaining a biopsy sample. Ultrasound imaging, on the other hand, is less revealing than MRI but provides the real-time images physicians need to visualize their target.

A team of engineers and medical researchers at UW-Madison is working with a Madison biomedical firm, Marvel Medtech LLC, to merge the best of these technology worlds.

The team is developing a new real-time visualization approach to using MRI in the breast biopsy process, an advance that could lead to far more precise biopsies, shorter procedure times and reduced anxiety for patients. “Ultrasound is the technology of choice right now for image-guided biopsies, primarily because it’s easy to use and offers the real-time imaging,” says Associate Professor Walter Block (left). “Clearly, radiologists need to have confidence when conducting a biopsy that they are in the lesion. But many of the lesions detected by MRI are not visible in ultrasound.”

Lesions not detected by ultrasound have a malignancy rate of above 20 percent. For that reason, the American Cancer Society

In the finance world, ROI, or return on investment, is a common performance measure that essentially tells investors whether the money they spent was worth it, or not.

In Professor Teresa Adams’ case, the investors were U.S. citizens, and the money they spent funded transportation projects via the American Recovery and Reinvestment Act.

On campus, Adams directs the Wisconsin Transportation Center. However, for nearly a year in 2009 and 2010, she worked on sabbati-cal in the U.S. Department of Transportation Office of the Secretary, initially as part of a team of economists that conducted cost-benefit analyses of each grant proposal. “It was very exciting to me because it was the first time since the Interstate Highway Act of 1956 that invest-ments were chosen to support a national strategy,” she says.

That strategy centered around outcomes that included economic competitiveness for the nation or region, safety for all modes of transportation, contributions to livable communities, environmental sustainability, and infrastructure state of good repair.

The department awarded 51 grants in February 2010 for innovative projects ranging from investments in an effort to reduce rail conges-tion in Chicago to a new streetcar line in a Hurricane Katrina-damaged area of New Orleans.

After her work on the proposal evaluation team concluded, Adams collaborated with the assistant secretary for transportation policy and experts in many transportation modes to define and draft performance metrics for each project.

That’s where the ROI comes into effect. “In this nation, we’ve been able to enjoy an economic advantage over other nations because of the efficiency of our transportation system, and in particular, our freight transportation system,” says Adams. “If we don’t keep up that efficiency and make wise investments, then we’ll fall behind and lose our ability to enjoy the quality of life we do.”

On September 4, 2006, Mark Wangler’s wife Kathy died of carbon monoxide poisoning in the couple’s Bath Township, Ohio, home. Yet, Wangler, who was sleeping in another bedroom, survived.

Detectives who visited the home as a matter of protocol began to wonder why only one spouse died—particularly since Wangler claimed the carbon monoxide accumulated because of a faulty ventilation system on the home’s hot water tank. Suspecting foul play, the detectives ultimately collected ductwork from the home, as well as the hot water tank, vent covers, hoses, carpet, Wangler’s diary, journals, computer equipment.

Then they called the FBI and the U.S. Environmental Protection Agency for help—but neither organization had the specialized knowledge to determine the real source of the carbon monoxide. The EPA told detectives to call Professor James Schauer.

Schauer is an international expert in using chemical tracers to identify sources of air pollution. His research group has analyzed pollutants in samples ranging from air in the Middle East to snow in the Greenland ice sheet.

The Ohio detectives asked Schauer to determine whether high concentrations of motor vehicle exhaust had passed through the Wangler home’s ventilation system. Carbon monoxide itself dissipates quickly; however, Schauer and colleagues at the Wisconsin State Lab of Hygiene documented very high concentrations of soot in the ductwork, carpet and other evidence taken from the Wangler home. They used chemical tracers to analyze the soot and determine that an internal combustion engine was its source.

Schauer wrote a report about the group’s findings and testified at Wangler’s trial in March 2011. Prosecuting attorney Juergen Waldick says their contributions were critical. “Schauer’s expertise and the work that the lab did was just essential to ruling out one of the possible defenses they had in this case,” he says.

On March 16, 2011, a jury found Wangler guilty of murdering his wife.

A new platform: DNA delivery, on demand

Chemical and Biological Engineering www.engr.wisc.edu/cheChemical and Biological Engineering www.engr.wisc.edu/che

A versatile new platform technology could enable doctors to release DNA locally in the body for a variety of therapeutic applications. Using a layer-by-layer fabrication process, Associate Professor David Lynn (left, pictured with PhD student Shane Beckler), can coat complex medical devices, such as vascular stents,

with alternating nanoscale polymer and DNA layers. When doctors insert these devices into the body, the coatings will break down and control how slowly or rapidly DNA is delivered. “The idea is local therapy,” says Lynn. “You can avoid some of the problems associated with administering something systemically.”

DNA needs a delivery agent to help it cross cell membranes and enable the cells to process it effectively. Positively charged, or cationic, polymers are a popular method for delivering DNA.

Lynn and his students make and synthesize cationic polymers that will assemble with DNA in solution to form nanoparticles or on surfaces to form films. They are layering their cationic polymers alternately with DNA to form multilayered thin films on medical devices, including stents, balloon catheters or microneedle arrays. “Layering allows you to control the amount of DNA or drug that’s incorporated, simply by the number of layers that you add, so that you can control the dose,” says Lynn.

Initially, he and his students focused on building stable polymer films that would “fall apart” in the body and release DNA. Now, they are taking this platform and making it useful for controlled, timed DNA delivery. With collaborators at UW-Madison and elsewhere, Lynn and his students are expanding their basic understanding into in vivo studies in animals. “We’re out of the tool-building phase and entering the phase where we can try some interesting things in a potential therapeutic context,” says Lynn.

Ultimately, Lynn, whose funding for the research comes from the National Institutes for Health, hopes use to this approach to coat devices with multiple different layers of multiple different drugs. “Then, you have a potentially sophisticated way to release multiple drugs in a controlled way over time, which is something that is difficult to do using conventional approaches,” he says.

In many industries, these advanced control methods lead to more efficient processes, energy savings, improved products and an increased bottom line, says Rawlings. “This is having an impact of savings on the order of $1 billion per year, just in the chemical process industries in North America, compared with the previous technology used for this,” he says.

His collaborators include Computer Sciences Professor Steven Wright and industrial partners in the Texas-Wisconsin-California Control Consortium. Consortia members fund a variety of Rawlings’ applied research, while National Science Foundation enables the fundamental research Rawlings can extend to larger classes of optimization and control problems.

the uncertainty and the way it depends on what we are doing,” says Maravelias. “It’s a hard problem that hasn’t been studied in

the literature.”In a general optimization problem, there is a set

of constraints that describes the problem and a set of optimization decisions. “In stochastic

programming, it’s the same idea, but we generate multiple scenarios describing different uncertainty realizations,” says Maravelias. “We have to make the decisions that would be good in all these scenarios.”

This multiple-scenario approach leads to very large computational

models, and another aspect of Maravelias’ work is developing the theory and solution

methods—algorithms—that can efficiently solve the models for real-world applications.

Maravelias, who in 2006 earned a National Science Foundation CAREER Award for this research, says the models also could extend into many industries in which businesses are developing new products with limited resources.

For industry, advanced control methods boost bottom line

In a chemical plant, a single raw product such as crude oil feedstock might be refined into many products, including gasoline, jet fuel and

asphalt. How one product becomes many requires extremely precise, tightly controlled integrated processes, and Paul A. Elfers Professor James Rawlings and his students develop the theory and algorithms to hone this control.

For many years, standard industrial controllers, coupled together, controlled multistage processes. Over time, these processes became more complex, and different parts of a process affected others. “It was hard to design local controllers to work together well to control a large, integrated system,” says Rawlings.

Rawlings and his students study the underlying theory of a control method called model-predictive control, which considers all variables in a large integrated system. The model uses plant data to forecast what the system will do, and then repeatedly optimizes the system over time. Rawlings’ group conducts research to verify and improve how accurately this happens. “Can you prove that the system will go to the set point you’ve selected?” he says. “Can you prove that it will be what’s called ‘robust’ to disturbances and model errors?”

His group also has developed algorithms that take thousands of variables into account and repeatedly and efficiently solve optimization problems in real time.

The models Associate Professor Christos Maravelias develops are somewhat like a crystal ball that pharmaceutical companies

can use to make research and development decisions about which drug formulations to develop.

Drug development is an expensive, highly risky, long-term endeavor. There might be hundreds of candidate compounds, for example, for just one “target” disease. Deciding which of those candidates to pursue involves extensive testing, time, and personnel and financial investments.

Maravelias develops methods that incorporate a company’s desired level of risk and account for all of this uncertainty. “From a portfolio of potential drugs, we try to develop methods that would allow us to select which ones to further develop, how to prioritize and also how to plan for our resources,” he says.

In drug development, the uncertainty is rooted in decisions people make. These decisions result in challenging optimization problems. “The underlying optimization problem is very interesting because of

Does ‘green’ behavior occur in a green building?

Completed in December 2010, the UW-Madison Wisconsin Institutes for Discovery Building marries majestic light-filled public spaces with state-of-the-art scientific

facilities. But while a hallmark of the building is its visual appeal, equally important to its users are the mechanical, electrical and other systems that operate behind the scenes.

In each of these systems, building designers included sensors that record data about everything from lighting and electricity use to occupancy and heating, ventilation and air-conditioning operations.

Using intelligent building automation software, Assistant Professor Carol Menassa, Adjunct Professor John Nelson and graduate students Elie Azar and Nathan Taylor are collecting this data to learn more about occupants’ energy use. They will use the information to verify and validate the designers’ assumptions about how the building and its systems should work. More importantly, they hope to understand how building occupants and their behavior will affect building performance.

Based on past research of buildings in other parts of the country, the researchers expect to find differences between predicted and actual energy use. “If we see these discrepancies, the next step is to understand why they are occurring,” says Menassa. “Is it the systems in the building, or is it the occupants?”

Occupants could affect energy use based on the length of time they spend in the building, and whether they leave equipment or lights on when they are not in use, among other factors.

Once the researchers gather data from the building systems, they will develop an agent-based model to simulate the ways in which people use the building. That simulation could lead to better building designs that more thoroughly consider occupant behavior. Additionally, it could help building owners enable users to under-stand and reduce their energy consumption. In fact, Menassa will assemble a “Green Team” of graduate students to discuss personal energy use with Wisconsin Institutes for Discovery occupants and assess the efficacy of this peer-to-peer approach to change.

Menassa recently received $282,576 from the National Science Foundation to fund this research.

barrier to developing thermoelectric devices beyond research labs. Silicon is the most abundant semiconducting material.

Thermoelectric devices are designed to preserve heat at one end and cooler temperatures at the other; good thermal conductivity does exactly the opposite by dissipating heat evenly to both ends. When silicon is grown so that at least one dimension is at the nanoscale, its nano-boundary scatters the quantum lattice vibrations, or phonons, that serve as primary heat carriers. This scattering is an effective way to reduce a material’s thermal conductivity.

Knezevic has discovered that growing silicon nanowires to a range of 20 to 50 nanometers is the optimal size to scatter phonons but not charge-carrying electrons. This range drastically reduces silicon’s thermal conductivity and a quantity known as the thermoelectric figure of merit, making it the “sweet spot” for silicon to demonstrate its optimal thermoelectric properties.

The researchers also are evaluating the thermoelectric behavior of various silicon nanomembranes with quantum dots inclusions and membrane-based heterostructures.

“Nanostructuring enables you to get surprising performance out of household materials, and we’re using silicon in ways we wouldn’t normally envision,” Knezevic says.

Silicon’s ability to dissipate heat, a property called high thermal conductivity, is part of the reason it is a popular material for electronics applications.

Yet when silicon is reduced to the nanoscale, it displays a very different property, becoming an efficient thermoelectric material that can convert heat into electricity (a process called energy harvesting) or produce cooling via an electrical current.

Associate Professor Irena Knezevic (pictured with postdoctoral research associate Edwin Ramayya, left, and postdoctoral fellow Zlatan Aksamija), and Erwin W. Mueller Professor and Bascom Professor of Surface Science and Materials Science and Engineering Max Lagally, and Physics Professor Mark Eriksson are exploring ways to develop silicon nanostructures that best take advantage of the material’s thermoelectric properties.

Knezevic is an expert in microscopic computer simulations, and her group helps guide experiments by Lagally, an expert in materials growth, and Eriksson, who measures the thermal and electrical properties of nanostructures.

Semiconductors with good thermoelectric properties typically are materials with a heavy atomic weight, such as bismuth telluride. However, tellurium-based materials are toxic and rare, which is a

Vining decided to eliminate the problems with these intermediaries. She modeled, constructed and tested a new class of linear generators that are wound-field devices, meaning the generator field is composed of coils, rather than permanent magnets, which are made from rare, expensive materials. Vining’s generator could be made from more common, ocean-friendly materials, such as copper and iron.

“Developing an efficient means for extracting energy from wave motion is poised to be the next research challenge in the field of electrical power,” says Grainger Professor Emeritus of Power Electronics and Electrical Machines Thomas Lipo. “Jennifer’s PhD on new wave motion generators introduces an important alternative and clearly places UW-Madison at the forefront of this rapidly developing technology.”

Mid-infrared semiconductor lasers release most energy as heat rather than light. To overcome this inherent deficiency, researchers have developed a quantum cascade laser structure, where electrons move like a ball falling down a ladder. The “ball” may hit the first couple of steps and emit a quantum unit of light, or photon, each time it falls from one step to the next. Eventually, though, the ball may veer off course and drop off the ladder entirely. This efficiency problem, called carrier leakage, results in heating and poor reliability, which currently is the major barrier to using continuous-wave, quantum-cascade lasers in most industrial applications.

Botez and Mawst have created structures that work more like a set of tiered boxes, with a ball getting caught at each stage of the structure. This ensures the electrons will not fall off the cascade structure, or leak, and thus continue to produce photons efficiently. The new tiered-box structures are called deep-well and tapered-active quantum cascade lasers.

Importantly, Botez and Mawst grow the new structures via a process known as metalorganic chemical vapor deposition, which is suitable for large-scale manufacturing.

Botez and Mawst also are co-founders of the startup Alfalight, and both say this previous experience will help them grow Intraband. “It’s really satisfying to see a concept as a product,” Mawst says.

New wave of energy research

Arenewable energy source that could serve the majority of the U.S. population often flows by unnoticed, even as it

continuously rolls and crashes onto the shores of a country searching for petroleum alternatives.

PhD student Jennifer Vining has brought the attention of Wisconsin Electric Machines & Power Electronics Consortium researchers to the sea. “Water is much more energy-dense than air, and you can feel this when you’re swimming, because it’s more difficult to pass your arm through water than air,” Vining says. “As such, a unit area of ocean has the ability to produce far more energy than the same area of wind.”

One of the most common types of ocean wave energy converters is known as a point absorber, which is a buoy-like device that heaves up and down with the waves. The point absorber is connected to a generator, which typically sends power via undersea cables to a substation on shore.

Waves produce a linear heaving motion in point absorbers, and current devices convert this energy into rotational motion to drive conventional rotary generators (like wind turbines). Commercial solutions for this conversion process include hydraulic intermediaries, which decrease system efficiency and reliability.

With second company, laser researchers are seeing new light

Two professors have formed a startup company to commercialize a nanoscale laser structure that could benefit a wide range of

industries. Intraband LLC was co-founded in 2008 by Philip Dunham Reed Professor Dan Botez and Professor Luke Mawst and has received recent funding from the U.S. Army and Navy Small Business Technology Transfer Programs. Botez and Mawst also have received a grant from the Wisconsin Alumni Research Foundation Accelerator Program, which will support more research toward proving their patented concepts.

“We have the ideas and now we’re gradually building toward making these devices a reality,” Botez says.

In the next two years, Botez and Mawst will build a prototype based on their concepts for a novel structure that could yield lasers twice as efficient as current continuous-wave semiconductor lasers emitting in the mid-infrared.

These lasers could be used in biomedical devices, environmental monitoring devices, missile avoidance systems and even food packaging processes. This wide range of applications is possible because the researchers have all but eliminated the temperature sensitivity for lasers operating in continuous-wave mode, meaning the laser emits uninterrupted, coherent light.

The more Professor Wendy Crone (above, with Tim Kamp) worked with biologists, chemical engineers, medical professionals and others, the more she realized she wanted to go back to school. Now Crone is studying polymeric hydrogels, a class of polymeric materials that incorporate 10 to 100 times more water than the polymer that holds them together. JELL-O and contact lenses are

common hydrogels. Crone and an interdisciplinary team are looking at stem cell response to a surrounding three-dimensional hydrogel matrix. The goal is to test the influence of hydrogel material properties and mechanical stimulation on stem cell differentiation.

It is possible that researchers could use hydrogels as scaffolding on which to coax stem cells into producing engineered tissues.

• Wisconsin Distinguished Professor Michael Corradini will study critical heat flux phenomena under high-pressure and low-mass flux conditions. Critical heat flux is one of the key physical phenomena that limit the allowable linear power for a nuclear reactor core design. Corradini will also conduct safety analysis research on the next generation nuclear plant.

• Associate Professor Todd Allen will develop advanced high- uranium-density fuels for light water reactors. Because highly enriched uranium may increase the danger of nuclear proliferation, researchers continue to improve low enriched uranium alloys with high uranium density. The challenge is to create a high-density fuel that can be manufactured and reprocessed.

Although Wisconsin is known for its inter-disciplinary research, building the bridge between disciplines requires time and effort. With a Career Enhancement Award for Stem Cell Research from the National Institutes of Health, Crone is taking courses, participating in training workshops, and engaging in stem cell research over the next two years to become a better collaborator with her colleagues in other disciplines.

Bridging the gap between disciplines requires Crone and colleagues to speak and listen in a perpetual state of translation. For example, “stress” has a very specific meaning to a mechanics professor but may mean something completely different to a biologist.

“The way a person is trained in a discipline causes them to approach problems in a certain way,” Crone says. “An engineer may approach a problem quite differently than a biologist. In order to collaborate, both have to understand how they look at the world differently.”

As part of her retraining, and with the help of her colleague and mentor Professor of Medicine Tim Kamp, Crone has to develop her own lesson plan. “Being a student again is great. It’s so easy to sit in a class and have information delivered to you in an organized way,” she says. “Beyond the classroom, we have to figure out what we need to know. You have to dig out what you need and structure it yourself.”

To deter nuclear terrorism, should we inspect all incoming freight?

Inspecting ship containers for nuclear weapons is a daunting task. More than 11.6 million cargo containers enter U.S. ports each year, with 32,000 maritime containers

entering ports each day. Ninety percent of containers enter through 10 of the highest-volume ports, but there are more than 300 ports operating in the United States.

The United States currently inspects about five percent of containers entering the country. With funding from the University of Southern California-based Center for Risk and Economic Analysis of Terrorism Events, Professor Vicki Bier conducted a decision analysis on the potential impact that 100-percent inspection and the threat of retaliation would have on deterring smuggling of nuclear weapons in container freight, as well as whether partial inspection might also have a deterrent effect.

“We attempted to quantify the model as best we could. It involves complex considerations. How confident can we be that there would be retaliation? How confident can we be that the smuggler believes there would be retaliation? What if the attacker has multiple weapons?” Bier says. “The analysis tells you under what conditions you could achieve deterrence. It is based on an assumption that the smugglers are operating rationally, which they may or may not be.”

Based on publicly available data, Bier’s team quantified a game-theoretic model of terrorist decision making to understand the subject. The results suggest that unless the defender imposes high retaliation costs on the attacker, 100-percent inspection is likely to be needed, and deterrence with partial inspection may not be achievable in practice even though it is possible in theory. On the other hand, when the defender can credibly threaten the attacker with costly retaliation, partial inspection may be sufficient to deter nuclear smuggling attempts. Thus, for policy debates about how to prevent nuclear terrorism, consideration of the diplomatic stance on retaliation is as important as, or maybe even more important than, debate about the optimal percentage of containers to inspect.

Hands-on engineering—the Camp Badger way

For six weeks in summer 2011, more than 200 kids and more than a dozen facilitators, many of them area teachers and UW-Madison

engineering students, hiked, bussed to, and generally scoured the UW-Madison campus, local attractions and area companies.

These educational excursions were all part of the 14th annual Camp Badger, a one-week residential program for Wisconsin and Minnesota

teenagers entering eighth grade. As campers, they explore the many aspects of an engineering education and the profession, all while living in a student dorm and experiencing life on a college campus. “We involve middle and high school teachers to run the camps,” says Professor Phil O’Leary. “One of our informal objectives is to have teachers experience camp, too. It opens their eyes to engineering and helps them in the classroom. We have teachers involved from Madison, Verona, Stoughton and Racine.”

This year, for the first time, Camp Badger held a session in River Falls, Wisconsin, thanks in part to a generous donation from 3M Corporation. The program continues to grow in number of students, activities,

locations and impor-tant demographics. “The percentage of girls involved in camp went up this year, as did the number of students on need-based scholarships,” says O’Leary. “A primary goal of Camp Badger is to offer an experience to kids who would not otherwise have the opportunity.”

Scholarships offset part or all of the cost of camp, based on a recommendation from teachers. Funding for camp comes from alumni, corporations and a small portion of fees paid to Engineering Professional Development short courses.

Many Camp Badger alumni have gone on to pursue undergraduate engineering degrees, often at University of Wisconsin schools, reflecting the impact of their experience. “It’s part of our social responsibility, both to our profession and to the state of Wisconsin,” says O’Leary.

Graduation ceremonies for the Master of Engineering in Professional Practice (MEPP) and Master of Engineering in Engine Systems

(MEES) draw people from all over the world. The 40 or so graduates often bring their children, parents, grandparents and significant others to celebrate.

“It is not unusual to have 200 people at the combined graduation ceremonies. The students are proud of their accomplishment and proud of their cohort. They want those close to them to meet the people they’ve been studying with for two years,” says Program Director Wayne Pferdehirt.

What is most striking about the graduation scene is that MEPP and MEES are programs delivered at a distance. The students come to campus for one week each summer, but otherwise, they work together online.

Instructors say the strong connection that students make with each other is due in part to EPD’s efforts to build learning communities. The programs are designed to get students to work together in project teams, and to interact extensively in online discussions. Each cohort has a wealth of experience, spread across job functions and industries, and the individual students quickly learn the benefits of sharing this experience in relation to the courses they take together. They are solving common problems and

find it very useful to see how their peers in other companies and other industries approach these problems.

Students also support each other in their day-to-day coursework. All are working adults and each one arrives with a different set of strengths. “In any of the courses, whether it be statistics, project management or technical communications, there will be some experts and novices. They learn that they can count on each other for moral support and for technical support,” says Pferdehirt.

At the beginning of the MEPP and MEES programs, students take a course called Network Skills for Remote Learners, where they learn to use the tools and techniques required for effective online work. At the end of this course, they are comfortable in the online environment and eager to meet their fellow students in the summer residency week which follows.

Other distance degree programs promote the idea that students should work together, but the EPD programs take that to a whole new level. The results can be seen in the bonds that students form and the contact they continue after graduation.

“There was a great deal of balance in the cohort,” says MEPP graduate David Gottshall. “Such professionals, such diversity, such technical competence. And what I really appreciated about our cohort was a lack of competitiveness. There was not a sense of pretense. Everybody was on the team. It didn’t matter what your need was from a fellow cohort, they were there.”

As a result of working with Rath, NeoClone was able to better engage and initiate clients early. That helped the company reduce the time from initial contact to the launch of production on projects by almost two weeks. “We still, in some ways, followed a process like we would a research program,” says NeoClone CEO Deven McGlenn (right). “We did things a certain way because that’s always the way we’d done them—which is not uncommon in the life sciences world. However, with the critical outside look that Frank and his team brought, we were able to identify a set of measurement points that allowed us to change the process in ways that created efficiencies.”

That’s a common issue in the biotech companies Rath has worked with. Biotech manufacturers often work with complex recipes to create products. There can be days when nothing seems to work right and production withers to a halt. But by applying industrial engineering principles, Rath helps companies define materials, conditions and processes so that when something goes wrong, employees have a strategy to see through the complexity and solve the problem.

“

When process equals progress: Building blocks for biotech businesses

You can’t solve a problem if you don’t know where to look,” says Faculty Associate Frank Rath (pictured left).

Rath is working to bring the same benefits of industrial engineering enjoyed by traditional manufacturers to the biotech industry. “It’s very fertile ground,” he says. “For the most part, scientists don’t view processes the same way that engineers do. They view what they do in the lab as more of a scientific art. The best scientists are artists. They don’t boil the business down to a defined engineered process. Going from customer contact to an actual order needs a process. Production needs to have a true, defined process.”

NeoClone is a Madison-based company that excels at producing monoclonal antibodies. Rath’s team interviewed NeoClone employees to better understand its products and processes and then formed a NeoClone team. The team identified company problem areas, helped create a flow chart, and performed an order fulfillment analysis, through which orders are followed through the company from initiation to completion.

Wisconsin is home to approximately 10,000 small to medium manufacturers, which provide approximately 430,000 jobs. UW-Madison has a long history of manufacturing research,

education and outreach, and the UW E-Business Institute (UWEBI) and its corporate membership arm, the UW E-Business Consortium, are especially active with the manufacturing industry. Directed by Robert A. Ratner Undergraduate Chair and Professor Raj Veeramani, UWEBI is a multidisciplinary center that conducts research on e-business strategies, emerging information technologies and innovative business practices.

UWEBI has a decade-long relationship with the Wisconsin Manu-facturing Extension Partnership (WMEP), which aims to keep state manufacturers competitive, profitable and growing in a global economy. The organizations currently are working together on a two-year initia-tive to introduce WMEP customers to the best practices that UWEBI and its affiliates have learned over the years. “We reach out to only the best organizations for partnership,” says Roxanne Baumann, WMEP director of partnerships and alliances. “UWEBI builds trust and communication with manufacturers and creates a safe haven for learning and coaching.”

Veeramani says working with WMEP allows UWEBI and its consor-tium members, which are typically large companies, to share lessons learned with the broader state manufacturing community. “This allows us to amplify the impact of those lessons,” he says.

In addition to workshops, webinars and confer-ences, UWEBI offers WMEP customers the opportu-nity to participate in graduate student projects that address a company’s specific challenges or needs.

In spring 2011, UWEBI students worked with Waunakee-based Hellenbrand Inc., which produces custom water-softener systems, and Madison-based Bock Water Heaters, among other compa-nies. At Hellenbrand, students helped the company rethink its entire sales and engineering processes as Hellenbrand prepared to adopt a new product configuration software tool.

With Bock Water Heaters, students redesigned the shop space and streamlined operations to make room for new model production. Bock now plans to apply principles from the project to other areas of the company. “Together we’re providing hands-on learning, skills and knowledge transfers that really enhance the competitiveness of small manufactur-ers in Wisconsin,” says Baumann. “By keeping their performance strong, we continue to build jobs and the state economy.”

access to these data by other UW researchers.”Zimmerman hopes to continue his affiliation with the

department as a professor emeritus and in “retirement,” he intends to develop a better system to meet the needs of patients during the process of transferring from one healthcare setting to another, such as from a hospital to nursing home. He also is passionate about reforming the policy of administering antipsychotic drugs to nursing-home patients who may not need them.

Ultimately, both Zimmerman and current CHSRA researchers plan to build on the center’s long tradition of healthcare performance measurement. “The major accomplishment of my work at CHSRA and as a member of the ISyE department has been to help people understand how to improve healthcare systems and evaluate those efforts objectively,” Zimmerman says.

Of the 10 themes that make up the core research program at the new Wisconsin Institutes for Discovery (WID), the mathematical

optimization group is especially well positioned to have a multi- disciplinary impact at the institutes and beyond.

The team is a blend of industrial and systems engineering and computer sciences faculty and will expand to include experts from other fields in the next year. Led by Professor Michael Ferris (also computer sciences), the group includes Associate Professor Jeffrey Linderoth and Assistant Professor Jim Luedtke, along with Professor Stephen Wright (also computer sciences) and Computer Sciences and Electrical and Computer Engineering Assistant Professor Ben Recht.

The WID group brings together a rare combination of researchers with a variety of optimization specialties who will study and develop new methods, as well as apply these methods, to a wide range of important real-world problems. The team’s dual emphasis on research and applications makes it unique.

Optimization experts tend to specialize in tackling problems that involve either discrete variables, which are essentially yes or no decisions, or continuous variables, where design parameters fall

along a continuum of values. Such optimization teams at other institutions tend to have expertise in one class of problems or the other. The WID team has experts in both.

To tackle real-world issues, the researchers will translate problems into mathematical equations that can be solved and analyzed, and develop the optimization methods for solving these problems. The team will work closely with other researchers to expand the use of optimiza-tion methods to their WID-sponsored projects, such as systems biology, epigenetics or medical devices. “UW-Madison has a long tradition of being a world-leading institution in mathematical optimization, and the institute will allow us to continue this tradition,” Linderoth says.

The group also will study complex problems beyond WID. Examples of ongoing projects include better-targeted radiation for cancer treatments, more efficient operating room scheduling in hospitals, and designs for more reliable electric grids. “The optimization group embodies the collaborative mission of WID,” Ferris says. “Our tools and techniques will provide a direct benefit to our collaborators, allowing them to more efficiently analyze and effectively model their data, whether the subject and variables are drawn from ecology, medicine, statistics, agriculture, engineering or genetics.”

Collaborative optimization simplifies real-world problems

As its 40th anniversary approaches, the Center for Health Systems Research and

Analysis (CHSRA) is at the beginning of new era. Professor David Zimmerman, who directed the center for more than 20 years, retired in summer 2011. Yet that doesn’t mean he or CHSRA are slowing down; as Zimmerman focuses on new projects, CHSRA researchers are expanding the center’s expertise.

Founded in 1973 by Professor Emeritus David Gustafson, CHSRA has become a dynamic center for developing and implementing healthcare performance measures. Among the center’s many accomplishments are the “CHSRA indictors” used by federal regulators and healthcare providers to target areas of nursing homes in need of improvement.

In the last decade, CHSRA has begun exploring ways to address healthcare efficiency, a critical issue in the U.S. healthcare system. The challenge requires multidisciplinary efforts, and CHSRA collaborates closely with local and national healthcare providers, purchasers and regulators. “We hope to build on our success by expanding the scope of CHSRA’s research to include care quality, cost and value issues in long-term care and other healthcare venues,” says Senior Research Scientist

Epitaxy, growth that controls the arrangement of atoms in thin layers on a substrate, is the fundamental technology underlying the semiconductor industry’s use of these new materials. By combining elements, researchers can grow semiconductor alloy materials with unique properties that make possible new kinds of sensors or high speed, low-power, efficient advanced electronics. It is the ability to grow them without detrimental defects that makes these alloys useful to the semiconductor industry. However, making high-quality crystals that combine two or more elements faces significant limitations that have vexed researchers for decades.

With this new method, researchers could develop better oscillators, sensors and optical devices that are important to the cell phones, cameras and computers we use everyday.

friction between quartz surfaces in the presence of water. The team discovered that in static, or non-sliding, contact, the rate of formation of chemical bridges across the quartz interface slows down with time because, once formed, these bridges interact with each other.

The phenomenon is particularly important because it implies that during the time when surfaces are stuck together, the strength with which the surfaces adhere to one another increases logarithmically

with time—a dependence that has been observed for these systems in laboratory conditions and used as a phenomenological

law in earthquake mechanics. Szlufarska also is applying her expertise in mechano-

chemistry to the effects of chemical environments on cell migration in the context of cancer research. In

particular, she is exploring how chemical pathways inside a cell, as well external chemical stimuli, couple to the ability of the cell to adhere to a

substrate and its ability to migrate.

An earthquake conjures images of massive tectonic plates shifting and ocean waves heaving across the planet. To understand such

interactions better, Associate Professor Izabela Szlufarska is looking at them on the molecular level.

Szlufarska researches the phenomena that result from coupling chemistry and mechanics, with specific focus on adhesion and friction. For example, her group has discovered that dry nanoscale contacts follow different laws of friction from those typically encountered in larger engineering contacts. In small enough contacts, friction can be described as a sum of forces that arise from individual bonds formed across the sliding interface. Shallow tectonic earthquakes can be viewed as frictional instabilities. Since water is ubiquitous in these environments, understanding the effects of water and humidity on friction is of critical importance.

Szlufarska’s group is performing quantum mechanical molecular dynamics simulations of

At one point during fabrication, the nanomembrane is wrinkled because the elastic strain is partially released.

The camera in your phone collects light on silicon and translates that information into digital bits. One of the reasons those

cameras and phones continue to improve is that researchers are developing new materials that absorb more light, use less power, and are less expensive to produce. Recent innovations by a team of materials science and engineering researchers now promise even greater opportunities in the growth of materials beyond silicon and other traditional semiconductors.

Research Assistants Deborah Paskiewicz and Boy Tanto, along with Scientist Donald Savage and Erwin W. Mueller Professor and Bascom Professor of Surface Science Max Lagally have developed a new approach for using thin sheets of semiconductor known as nanomembranes.

Controlled stretching of these membranes via epitaxy allows the team to fabricate fully elastically relaxed silicon-germanium alloy nanomembranes for use as growth substrates for new materials. The team grew defect-free silicon germanium layers on silicon substrates and then released the silicon germanium layers from the rigid silicon, allowing them to relax completely as free-standing nanomaterials. The silicon germanium film is then transferred to a new host and bonded there. From this stage, a defect-free bulk silicon germanium crystal can be grown (something not possible with current technology), or the silicon germanium membrane can be used as a unique substrate to grow other materials.

An engine block cast from aluminum or magnesium-matrix nanocomposites can be much lighter than one cast from aluminum alone. Similarly, a power-plant pressure vessel made from advanced steel that can withstand higher temperature and pressure without deforming could burn more efficiently and produce less pollution. Researchers continue to create new

materials with properties that promise to reduce weight, increase performance and save energy in numerous applications. But in many cases, before these advanced materials can be put to use, someone has to figure out how to weld them.

With funding from the National Science Foundation, Professor Sindo Kou (pictured with graduate student Dustin Wagner) and colleagues from Ohio State, Lehigh University and the Colorado School of Mines have formed the Industry/University Collaborative Research Center for Integrative Materials Joining Science for Energy Applications. The center seeks to extend the service lifetime of welds in the existing energy infrastructure, increase the efficiency of advanced welding materials, and create the technologies required to join those materials for use in new infrastructure.

Industry partners such as Hobart Brothers, Cummins and NASA have joined the center to explore options for creating or improving new joining science. Hobart Brothers is working with Kou to develop new welding filler wires that will make welds not only resistant to creep (deformation at high temperatures) but also tough enough to resist cracking when the pressure vessel is cooled down. Cummins is working with Mechanical Engineering Professor Xiaochun Li, the associate center director, on the weldability of cast metal-matrix nanocomposites for engines. Arc welding is routinely used to repair cracks and surface defects of metal castings, but metal-matrix nanocomposites are so new, no one has devised a method to weld them.

NASA seeks to weld metals by traversing a rotating rod along the joint between two plates that are held tight together under thousands of pounds of pressure and softened in the area ahead of the rod by localized heating. The heating prevents the rod from wearing out. The pressure and heat create atomic-level contact between the metals, and they form new bonds, or weld, without melting. The process, called thermal-stir welding (as opposed to friction-stir welding), has been used successfully with titanium alloys. Now, NASA will work with Kou’s team to apply it to energy-related materials.

Power steering: A system for more capable catheters

David

Atrial fibrillation is a condition where the upper chambers of a patient’s heart beat irregularly, which can cause blood to pool and increase the risk of stroke-causing clots. Treatment is difficult: A physician has to maneuver a catheter around a patient’s chest cavity to the diseased regions of the heart, which are then frozen or burned.

A robotic catheter is articulated and moves in and out. In theory, a clinician controls it by pulling on the cables that run along the outside of the catheter, but in reality, friction develops and robs the cables of tension. This is a particular problem when clinicians are trying to operate the catheter in an open body cavity rather than snaking the device through a vein or artery.

“There isn’t a one-to-one relationship in how much you pull and the catheter’s response,” says Assistant Professor Michael Zinn, (pictured, with Nicola Ferrier) who is investigating model-based control strategies to improve the performance and efficacy of these catheters. Zinn is developing a closed-loop control system that will adjust a catheter electronically to go where a physician directs it and correct for errors.

He is collaborating with Professor Nicola Ferrier to develop better imaging of a catheter during a procedure. Current imaging is done via X-rays, which can’t be delivered continuously to patients, so physicians can only view the catheter intermittently. Zinn and Ferrier are merging the benefits of various computer- and radiation-based imaging technologies to develop more advanced techniques to determine where a catheter is at all times.

Along with developing the algorithms and sensing techniques and implementing them in hardware, Zinn’s team is modeling the new device and studying the underlying physics of how the catheter moves.

Improved catheter control has applications in any minimally invasive procedure that uses a flexible robotic device. Creating a more seamless and intuitive system may broadly expand the number of doctors who will use these technologies, Zinn says.

“Current catheters are resigned to poor performance. If successful, this could significantly increase the capabilities of most types of flexible robotics and increase the effectiveness of procedures that use them,” he says.

Aluminum and magnesium alloys hold great potential for manufacturers, as

these alloys are much lighter than traditional high-strength materials such as iron and steel. However, most high-strength aluminum and magnesium alloys are difficult to cast because these materials tend to crack as they solidify in casting molds.

This “hot tearing” is a major barrier to expanding commercial uses for these alloys. Companies that use hard-to-cast alloys must cut shapes out of large chunks of the materials with machines—an expensive process that prevents most manufacturers from using alloys to cast products with geometrically complex shapes.

Led by Professor Xiaochun Li, researchers in the Nano-Engineered Metals Processing Center have developed a method to inject

Future projects will include exploring how to enhance nanocomposite aluminum’s high-temperature properties for power lines or conductor plates and using nanocomposite magnesium to develop body implants and other biomedical devices.

The center’s emphasis on industrial application is supported by a five-year, $10.1 million grant from the National Institute of Standards and Technology and joint venture partners. Li is planning to form a nano-engineered metal processing consortium, and more than 60 companies have already expressed interest in working with the center.

“Our research really brings a fresh, new frontier to the traditional metals industry,” Li says. “We’re building a new nanotechnology industry on top of this traditional industry.”

Astrophysics instruments that measure very faint, distant sources of light need to be very cold to be sensitive enough

to detect individual photons. These detectors work by measuring the change in temperature that occurs when a single photon hits the detector and deposits energy. Because this temperature rise is extremely tiny, only a very cold semiconductor is sensitive enough to detect it.

Some of the world’s most sensitive X-ray and infrared detectors operate at temperatures below 1 degree Kelvin.

Although space is very cold, the detectors used in orbiting tele-scopes must be cooled artificially if they are to reach temperatures below about 40 Kelvin, because thermal radiation from the earth and sun warms them.

That’s where Assistant Professor Franklin Miller comes in. Miller, who got his start working on projects like the James Webb space telescope at NASA’s Goddard Space Flight Center, works in the field of sub-Kelvin cryogenics to cool sensitive instruments to temperatures colder than 1 degree Kelvin.

In space, astrophysics detectors operate at temperatures of about 50 thousandths of a Kelvin, or 50 millikelvin. But Miller is

and evenly disperse nanoparticles into metal melts. These nanoparticles, which are typically ceramic, induce nucleation in an alloy to refine grain size while shortening its solidification time, which helps prevent hot tearing. Center researchers also are testing an initial industrial system that can handle 20 to 50 pounds of nanocomposite aluminum, a scale necessary for manufacturers to produce actual products.

The center’s industrial partners are ready to begin implementing the research and new system, and Wisconsin-based Eck Industries and Oshkosh Corp. will be first. One early project with Oshkosh will use an aluminum alloy instead of steel for an armored vehicle door. Currently, a gallon of gas to fuel one of these vehicles on a battlefield costs as much as $300. Using lighter high-strength materials could help reduce such costs.

striving to make them even colder—on the order of 20 millikelvin. Although that difference might seem small, only about a hundredth of a degree Fahrenheit, it’s still two and a half times colder than previously achieved in space. Reaching such temperatures in space

would pave the way for a new generation of even more sensitive instruments, says Miller.

His project involves adapting dilution refrigeration, which uses an endothermic reaction between superfluid helium-4 and helium-3. Mixing the two isotopes causes them to cool and has been used in laboratories since the 1970s to reach temperatures below 20 millikelvin.

Currently, standard dilution refrigeration won’t work in micro-gravity, but Miller is currently testing two improvements: a more compact pump with no moving parts, and a means of separating the two isotopes after the mixing that relies on surface tension, not gravity. He expects to have a working prototype around 2013.

“If we can get the detectors to be more sensitive we can under-stand more about how the universe works and may answer some important questions about why the universe does not appear to be working as everyone thought it should,” he says.

Most of the people who were in the Geological Engineering Program (GLE) with me got involved because we enjoy the out-doors,” says Sam Freitag (pictured). “We liked all the time we got

to spend on camping trips for geology and doing outdoor field work, but we also liked the environmentally sustainable aspect of our learning.”

Freitag, who earned his bachelor’s degree in geological engineering in May 2011, is among an increasing number of engineering students who are choosing to major in GLE at UW-Madison.

With its 25-year anniversary approaching in 2013, the Geological Engineering Program has grown from just 18 undergraduates in 2009 to nearly 60 students—with an additional 30 graduate students— in fall 2011.

In part, that uptick in enrollment is due to an updated curriculum and improved marketing that emphasize the societal and environmental benefits of work in the discipline, says Wisconsin Distinguished Professor of Civil and Environmental Engineering and Geological Engineering Craig Benson. “Realigning ourselves with themes that are very relevant to the future is just a tremendous advantage for us,” he says.

Geological engineers find the best ways to use the earth’s resources to solve technical problems while protecting the environment, and they work in such industries as energy, mining and environmental consulting, among many others.

At UW-Madison, GLE undergraduates can gain technical expertise through one of five technical tracks: energy, minerals and mining; sustainability and the environment; geohazards; groundwater and surface water; and infrastructure. “I like the strong emphasis the GLE program puts on sustainability,” says Freitag, who recently took a job at a new underground mining project near Phoenix, Arizona. “It focuses on being able to use the resources we have in a sustainable, environmentally conscious manner. I try to keep that in mind when I am working, too.”

In addition to a bachelor’s degree in engineering, GLE students also earn a dual degree in geoscience through the UW-Madison College of Letters and Science. “The curricula naturally complement each other,” says Benson.

Douglas Dettmers, who earned his dual bachelor’s degrees in 1997, has spent his entire career working in the geotechnical engineering field and now is a regional manager with Gestra Engineering of Milwaukee. He says the cross-departmental GLE curriculum enabled him to add skills that have benefited his career.

“There was a real range of options for the upper-level elective courses and I had the ability to select classes during my undergraduate program that specifically applied to my future employment,” says Dettmers. “The non-elective courses, which included geology, hydro-geology and geotechnical courses, exposed me to a broad range of technical issues. I find that I often refer to some of the reference material from these courses when I encounter non-typical conditions.”

At UW-Madison, GLE students receive the kind of broad education that enables them to bridge boundaries between engineering and the natural sciences. And GLE students themselves are entering with a richer diversity of backgrounds, thanks in part to Research Scientist Sabrina Bradshaw. A GLE alumna who serves as the program’s undergraduate recruiter, Bradshaw manages the GLE undergraduate research program and talks about GLE with students at the university’s freshman orientation program.

Currently, nearly 50 percent of GLE students are women. “Sabrina is a role model who is bringing different people into the program,” says Benson, who also sends a personal letter to every entering engineering student. “We’re going to have a diverse workforce everywhere and there’s great value in diversity of ideas. That’s very important, and I want to embed this in the GLE program for the future.”

Megan Jehring, a senior who is planning to pursue a master’s degree in geological engineering, chose GLE because it combined her interest in geology and her desire to pursue a field that involved using math skills. “I really enjoy how widely applicable the major is to society, such as construction and environmental issues,” she says.

An active member of the UW-Madison student chapter of the Association of Environmental and Engineering Geologists, Jehring says she appreciates the GLE program’s close-knit feel. “The program is very diverse, but also very welcoming,” she says. “The faculty, staff and students make up a supportive community that feels more like family. I’ve made many connections that have helped me gain internships and recommendations for grad schools and careers in industry.”

The project was one of five created during ESP participants’ Introduction to Engineering class. The students’ display would magnify texts to make them visible to commuters without drawing too much of their attention from the road ahead.

Held six weeks each summer, ESP is the longest-running pre-college outreach program at UW-Madison, about to enter its 40th year. It targets minorities, women and first-generation college students—people who traditionally are underrepresented in science, technology, engineering and math. The academic core of ESP—college-level instruction in science, math and technical communications—gives students a realistic expectation of what to expect in a demanding college environment, while guest speakers from industry and tours of companies such as Rockwell Automation and Abbott Laboratories enable them to learn about jobs in scientific fields.

Students come to ESP from all over the country. Nearly all ESP alumni ultimately attend college at institutions ranging from UW-Madison to MIT and Stanford. Eighty percent of ESP alumni apply to UW-Madison as undergraduates—and 90 percent of those students enroll in the College of Engineering.

Sourinthone Bounket’s experience in ESP in summer 2011 typifies the program’s success in attracting engineering students. “I’ve been really undecided on what kind of engineering I wanted to do, and I was hoping that ESP would help me decide,” says the Milwaukee Rufus King High School senior. “Now I want to do chemical engineering.”

ESP participants discuss their design with College of Engineering Dean Paul Peercy.

PREPARING KIDS FOR COLLEGE

When a group of high school students gets together to decide the best way to text while riding a bicycle, the expected result would probably involve mangled spokes and a broken limb or two.

But during the UW-Madison Engineering Summer Program (ESP), high school juniors and seniors approach such problems as real-world engineering challenges in which they apply college-level coursework in physics, chemistry, calculus and technical communications. “Our project focused on making communication a lot easier to do during everyday use of your bike. That way, you wouldn’t miss an important call or important issues,” says Geraldo Herrera, a high school senior from Tucson, Arizona.
