Steven Gorelick is a professor of Geology and Environmental Sciences, and Geophysics, at Stanford University in California. He obtained his M.S. and Ph.D. degrees in hydrogeology from Stanford University. His research interests include groundwater contamination, problems of water supply, groundwater resource policy, innovative methods for aquifer remediation, groundwater flow and contamination transport model development/analysis, and uncertainty analysis for hydrogeologic problems.

Elisabeth Holland is a scientist at the National Center for Atmospheric Research and a professor at the newly formed Max Planck Institut für Biogeochemie in Jena, Germany. Her research involves the global nitrogen cycle focusing on the links between atmospheric chemistry and terrestrial ecology. More specifically, she has focused on quantification of regional and global nitrogen deposition; its effects on terrestrial ecosystems, particularly carbon uptake, and evaluation of N deposition predicted by chemical transport models. She received her Ph.D. in ecology from Colorado State University.

Daniel Krewski is professor of medicine and of epidemiology and community medicine in the Faculty of Medicine at the University of Ottawa, and adjunct research professor of statistics at Carleton University. He earned his M.S. and Ph.D. in mathematics and statistics from Carleton University, and his M.H.A. from the University of Ottawa. Dr. Krewski is associate editor of Risk Analysis, Risk Abstracts, and the Journal of Epidemiology and Biostatistics.

Robert J. Naiman is a professor in the School of Fisheries at the University of Washington. He received his Ph.D. from Arizona State University in Zoology with an emphasis in ecosystem science. His research interests include river ecology, riparian corridors and watershed management.

Elinor Ostrom is the Arthur F. Bentley Professor of Government in the Department of Political Science and the Co-Director of the Workshop in Political Theory and Policy Analysis and the Co-Director of the Center for the Study of Institutions, Population, and Environmental Change at Indiana University. Her research work has focused on the study of institutions at a local, regional, and global level. 

Michael Rosenzweig is professor and former head of ecology and evolutionary biology at the University of Arizona. He received a Ph.D. in zoology from the University of Pennsylvania. He uses mathematical modeling to study species diversity, habitat selection, and population interactions. He also studies desert rodent community ecology.

Vernon Ruttan is a Regents Professor in the Department of Applied Economics at the University of Minnesota. He received his Ph.D. from the University of Chicago. His research interests include the economics of technical and institutional change, and economic development and foreign assistance policy.

Ellen Silbergeld received her Ph.D. from the Johns Hopkins University. She is currently Professor of Epidemiology and Toxicology in the Departments of Epidemiology and Preventive Medicine at the University of Maryland Medical School, and Director of the Program in Human Health and the Environment. Her research interests include neurotoxicology and environmental toxicology; and the adverse effects of chemicals and drugs on the development of the CNS, reproductive, and immune systems.

Edward Stolper is the Chairman of the Division of Geological and Planetary Sciences and the William E. Leonhard Professor of Geology at the California Institute of Technology. He received his Ph.D. from Harvard University. Dr. Stolper is recognized for illuminating the chemical differentiation of the Earth through creative experimental and theoretical studies of the density relations between rock melts and crystals at great depth in the Earth and the role of chemical speciation of dissolved water and carbon dioxide in determining the properties of magmas.

B.L. Turner II is the Milton P. and Alice C. Higgins Professor of Environment and Society at Clark University. He received his Ph.D. in geography from the University of Wisconsin, Madison. His research interests are human-environment relationships, both contemporary and historic, including land use/cover in global environmental change, small holder agriculture in the tropical world, and the cultural ecology of the ancient Maya.
