Prof. Lisa Alvarez-Cohen
University of California, Berkeley
LISA ALVAREZ-COHEN (NAE) is the Fred and Claire Sauer Professor of Environmental Engineering in the Department of Civil and Environmental Engineering at the University of California, Berkeley. Her research areas include environmental microbiology and ecology, biotransformation and fate of environmental contaminants, nutrient cycling in soils, and innovative molecular and isotopic techniques for studying microbial ecology of complex communities. Specifically, her research focuses on the application of omics-based molecular tools and isotopic techniques to understand and optimize the bioremediation of emerging and conventional environmental contaminants by naturally occurring microorganisms and to facilitate beneficial carbon cycling in the environment. Bioremediation and nutrient cycling are processes that rely upon complex mixed microbial communities that interact to catalyze important reaction pathways. Dr. Alvarez-Cohen is an associate editor of Environmental Engineering Science. Her previous NRC service includes the Committee on USGS Water Resources Research, the Committee on In Situ Bioremediation, and the Committee on Source Removal of Contaminants in the Subsurface. She received her B.S. in engineering and applied science from Harvard University and her M.S. and Ph.D. in Environmental Engineering and Science from Stanford University.
Dr. J. Carlos Santamarina
Georgia Institute of Technology
CARLOS SANTAMARINA is the Goizueta Professor with the School of Civil and Environmental Engineering at the Georgia Institute of Technology. His research focuses on the fundamental study of soils and subsurface processes. The implementation of this research has involved the development and utilization of particle-level testing methodologies, high-resolution process monitoring systems (including combined elastic and electromagnetic waves), and inverse problems. These conceptual and experimental frameworks have allowed the study of problems in civil engineering systems (dynamic soil response, underground excavations), mining (clay minerals and crushed rock), and resource recovery (petroleum and methane hydrates). Dr. Santamarina?s current research emphasis is directed towards engineered particulate systems and energy-related geotechnology. He has co-authored two books which summarize salient concepts and research results. He is a Corresponding Member of the Argentinean National Academy of Sciences and the National Academy of Engineering. He holds a Ph.D. from Purdue University, M.S. from the University of Maryland, and B.Sc. from Universidad de Cordoba.
Dr. Herbert H. Einstein

Dr. Franklin M. Orr, Jr.
FRANLIN ORR, Jr (NAE), is the Keleen & Carlton Beal Professor in the Department of Energy Resource Engineering, director of the Precourt Instutute for Energy, senior fellow at the Precourt Institute for Energy, and senior fellow at the Woods Institute for the Environment at Stanford University. His research focuses on the physical mechanisms that control flow of multiphase, multicomponent fluids in the subsurface, using a combination of experiments and theory. The theory part includes numerical simulation of flow in heterogeneous porous rocks and coalbeds, often using streamline approaches, and it also involves solving by analytical methods the differential equations that describe the interactions of complex phase equilibrium and flow (porous rocks containing more than one flowing phase can sometimes act like a chromatograph, separating components as they flow). The experiments are used to test how well the models describe reality. Applications of this work range from enhanced oil and gas recovery to geologic storage of carbon dioxide (to reduce greenhouse gas emissions) to the transport of contaminants in aquifers. Dr. Orr is a current member of DELS. He received his B.S. from Stanford University and his Ph.D. from the University of Minnesota, Minneapolis, both in chemical engineering.
