COURSES TAUGHT Environmental Nanotechnology

This course introduces the basic science and engineering concepts of nanoscience/nanotechnology and to present the scientific, societal, and cultural issues surrounding the introduction of nanotechnology into the global market place. Students discuss the opportunities for nanotechnology to improve the quality of life, as well as the potential negative consequences of this emerging field on the environment and human health. The goal is to increase awareness of how nanomaterials/nanotechnology interact with the natural world, and

at the same time stimulate students who are focused on careers in environmental engineering to consider possible nanotechnology-based solutions to environmental problems (e.g. energy production, groundwater remediation).

Environmental Engineering/ Environmental Engineering Laboratory

Provides a scientific and engineering basis for understanding environmental issues and problems including environmental chemistry, material and energy balances, physical processes and biological processes affecting surface and ground water quality, and introduces concepts of sustainability and environmental nanotechnology. Simple quantitative engineering models are developed, and qualitative descriptions of environmental engineering control technologies are presented. Laboratory experiments illustrate the basic principles of environmental engineering including environmental chemistry and physical and biological processes. The course provides hands-on experience measuring basic chemical and biological water quality parameters.

Characterizing and Analyzing Environmental Samples and Systems

I developed this course to familiarize graduate students with laboratory protocols for the analysis of water, wastewater, and soil used in scientific research, and to teach them to write scientific papers. The course goals are to 1) introduce students to the principles of environmental sampling and sample analysis, 2) provide familiarity and hands on experience with analytical tools used in environmental engineering research and practice, and 3) prepare students to write technical papers/reports and make technical presentations. Emphasis is on understanding the theory behind the techniques; rather than simply performing the analyses. The basic elements of an engineering/science publication are presented.

Fate, Transport, and Physicochemical Processes of Organic Contaminants in Aquatic Systems

Presents factors governing the behavior of hazardous organic chemicals in the environment: distribution among air, water, and solids. Provides and understanding of how a chemical's properties, equilibrium and rate principles, and relevant chemical transformations affect the distribution of pollutants in the environment.

Water Quality Engineering/Water Quality Laboratory

Provides an introduction to the fundamentals and engineering aspects of water quality. Basic principles of water chemistry; physical, chemical and biological phenomena affecting water quality are presented, and application of these concepts to a description of water quality changes that may occur in treatment processes and in natural-water environments, including water and wastewater treatment systems and groundwater. Labs demonstrate techniques for measuring and evaluating water quality and pollution parameters, and illustrates principles of dilute aqueous chemistry and processes affecting water quality. Measurements include titrimetric, spectrometric, potentiometric, and reductive/oxidative techniques.

ACTIVE RESEARCH PROJECTS I have three synergistic areas of research including 1) sustainable development of nanomaterials and development of nanotechnologies for water treatment and groundwater remediation, 2) Managing the impacts from fossil energy, and 3) innovative remediation methods for contaminated sediment, groundwater, and industrial brines. A brief synopsis of each is provided below. Sustainable development of nanomaterials and development of nanotechnologies for water treatment and groundwater remediation

Nanomaterials and nanotechnologies offer the potential to improve the quality of life and the environment through e.g. enhanced water treatment, efficient alternative energies, improved drug delivery and diagnostic tools, but responsible and sustainable development of nanotechnologies must include an a priori understanding of the risks they pose, including their fate and transport in the environment, and their potential toxicity. I have several projects assessing the biogeochemical fate and toxicity of engineered nanomaterials in environmental media. This is a multidisciplinary effort involving graduate students and faculty from Environmental Engineering, Chemistry, Chemical Engineering, Biomedical Engineering, and Biology.

Managing the Impacts from Fossil Energy

Sustainable energy production will ultimately require a shift to renewable energy sources, however this shift will not be rapid due to the high capital costs of changing the current infrastructure for generation and distribution of energy, deficient technical capability to create functional renewable energy technologies, and the advent of new technologies for extracting natural gas. In the interim, we will rely on carbon capture and storage (CCS) to curb CO2 emissions from fossil fuels. Technologies are needed to capture CO2 from

Innovative Remediation Methods for Contaminated Sediment, Groundwater, and Industrial brines

Remediation of sediment, groundwater, and industrial brines is costly and in many cases too few viable alternatives exist. Research in this area has consisted of 1) developing and evaluating sorbent-amended sediment caps capable of cost-effectively containing or treating sediment contaminants in situ, including determination of the physicochemical process affecting the performance and longevity of these enhanced sediment caps, and documenting their ability to perform in the field; 2) Developing novel materials for remediation of NAPL-impacted groundwater; and 3) electrode-based solutions for sediment contaminants and industrial brines.
