What do our competitors say?

2010 External Review Committee Report “If Berkeley is arguably the crown jewel of

America’s research-intensive universities, then EECS is arguably the crown jewel of Berkeley.”

“It is unsurpassed as a training ground both for the next generation of scholars and for the next generation of practitioners.”

“The research programs in Berkeley EECS are arguably the best in the world. Over many decades, Berkeley EECS has consistently opened up new areas of research for others.”

Berkeley EECS Research Style

Work together on really important problems No matter how hard

Have ideas with impact

Produce great students

29

Research Styles: Collaboration

Advisor and student working together Most meet at least weekly

Advisor and several students working together

Several faculty and many students Sensor Networks, ParLab, Nanolab, BWRC,

BSAC Groups of students with faculty guidance

E.g., Probabilistically Checkable Proofs - PCP

31

Research Retreats Project Reviews with Outsides

Twice a year: 3-day retreat at nice place

Faculty, students, staff, industry Industry visitors supply feedback Faculty members listen to it! High-intensity informal exchanges Builds team spirit

Experience shows that research retreats are the key ingredient in the success of large-scale (10-25 person) projects

EECS

Harnessing physical processes to perform logically defined functions Everything from band-gap phenomena to

Google and Avatar Dense interconnect between EE and CS,

Our General Approach to the PhD

We want you to acquire great minds Deep, broad, skilled in the art of creation Much further beyond your current self than you are

beyond your high-school self It’s important to learn new ways of thinking

Multidisciplinary research projects Courses in related areas of EE and/or CS Courses in related disciplines: statistics, mathematics

(geometry, logic, …), molecular biology, materials science, quantum physics, …

We want you to have a good time doing it (Ask the current students about this part.)

Our approach seems to be working

The future of EECS Radically new physics at the bottom: nano,

quantum, negative capacitance… Redesign the hardware stack, rethink levels of

separation, retool the design industry New machine architectures: massively parallel,

probably stochastic, possibly quantum; and new ways to program them

Redesign the communication stack top-to-bottom: clean slate

Intelligent human-scale robots Information systems that know everything As-yet-unimagined forms of education,

entertainment Increasing extroversion: engaging with and solving

the problems of society

Why do graduate study in EECS @ UC Berkeley?

48

But, …

49

Berkeley’s financial situation Total campus spending increased in 2008-9 vs 2007-8

Research activity very healthy EBI ($500M over 10 yrs) is the largest grant to any university in

history Berkeley will have 70 faculty searches next year and following State support functions analogously to endowment, bridging gap

between tuition and the operating budget Tuition is rising, as is federal support

UC 20% drop in state support Equivalent to ~5-6% of campus budget In-state undergraduate tuition increased to ~ $11K (vs ~$38K peers) Proportion of out-of-state students will go from 8% to ~20% Actively diversifying income stream with professional masters, etc.

Stanford’s endowment lost 27% 9/08-8/09; 500+ layoffs, faculty hiring freeze

MIT’s endowment lost 21% 7/08-6/09; $125M budget cut, freeze

50

Didn’t the faculty have a pay cut?

54

The situation for PhD students PhD students don’t pay fees or depend on

state funds Bit more expensive for the faculty member

Campus fellowships for EECS more than doubled in 2010 Further increase in 2011

EECS research dollars up around 15% over 5 years to ~$65M/yr Not including new $25M NSF STC in low-power electronics

Most PhD students are paid 100% (i.e. double stipend) in summer

Campus-wide trends since 2001

40% increase in PhD applicants Increase in offer acceptance from 45% to 55% 124 NSF fellows in 2009 (10% of US total)

110 at MIT, 72 at Stanford Berkeley has more Sloan Fellows than any other

institution, indicating quality of younger faculty $155M for PhD fellowships in current campaign

56

The bottom line

All major institutions took a hit; the appropriate response is collaboration - e.g., work on federal science policy

Universities are very robust and long-lived, whether private (Harvard, MIT, Stanford) or public (Berkeley, Oxford, Cambridge)

Make a choice on the scientific merits; the rest will take care of itself
