Committee Biographical Information

Michael T. Clegg (Chair) is emeritus professor of biological sciences in the Department of Ecology and Evolutionary Biology at the University of California—Irvine. From 2000 to 2004, he was the founding director of the Genomics Institute at the University of California—Riverside, where he was also dean of the College of Natural and Agricultural and Sciences from 1994 to 2000. Clegg’s research specialty is population genetics and molecular evolution. He is the chair of the U.S. National Committee for the International Institute for Applied Systems Analysis. He was elected to the National Academy of Sciences (NAS) in 1990 and as a fellow of the American Academy of Arts and Sciences in 1992. He was elected Foreign Secretary of the NAS in 2002, serving until 2014. He was president of the American Genetic Association (1987), president of the International Society for Molecular Biology & Evolution (2002), and chair of the Section on Agriculture, Food, and Natural Resources of the American Association for the Advancement of Science (2003). He was vice president of the International Council for Science and cochair of the InterAmerican Network of Academies of Sciences. He received a B.S. in agricultural genetics and Ph.D. in genetics from the University of California—Davis.

S. Carolina Córdova is an assistant professor and statewide soil health specialist at the University of Nebraska—Lincoln (UNL). She directs Nebraska’s Soil Health Program, fostering collaborative soil health research, extension, and teaching across the state. With an emphasis on sustainable agricultural intensification, her work centers around enhancing carbon sequestration and reducing reliance on synthetic fertilizers. She led the Bioenergy System Community within the American Society of Agronomy, serving as elected leader (2022) and vice leader (2021). Additionally, she has organized symposiums at meetings of the Agronomy Society of America, Crop Science Society of America, Soil Science Society of America, and GLBRC and at All-Scientist meetings of the Long-Term Agroecosystems Research Network (LTAR) of the USDA Agricultural Research Service (ARS). Córdova received the Early Career Award from the LTAR International Network under ARS. Córdova received a B.Engr. from Tecnica del Norte University, Ecuador, and Ph.D. in soil science from Iowa State University. She conducted postdoctoral research at the W.K. Kellogg Biological Station at Michigan State University. Her postdoctoral advisor is a member of the author team that prepared the analyzed white paper.

Eric A. Davidson is a professor of the Appalachian Laboratory of the University of Maryland Center for Environmental Science, where he served as director for 6 years. Earlier, he worked for 22 years at the Woods Hole Research Center, including a term as president and executive director. He served as the North American center director for the International Nitrogen Initiative and NASA project scientist for the Large-Scale Biosphere-Atmosphere Experiment in Amazonia. His current research includes terrestrial nutrient cycling, including the effects of land use and management in forests and agriculture on water quality and GHG emissions. Davidson is a past president and fellow of the American Geophysical Union, chair of its Ethics Committee, fellow of the American Association for the Advancement of Science, and Web of Science Highly Cited Researcher. He serves as senior editor for AGU Advances and was an editor for Global Biogeochemical Cycles, Global Change Biology, and Soil Science Society of America Journal. Davidson is on the Multidisciplinary Expert Scientific Advisory Group of the United Nations Environment Programme and recently completed a Jefferson Science Fellowship of NAS, where he served as a science advisor to the Office of Environmental Quality at the U.S. Department of State. Davidson received a B.A. in biology from Oberlin College and Ph.D. from the Department of Forestry at North Carolina State University.

Bruce A. McCarl is a University Distinguished Professor at Texas A&M. As an agricultural economist, his work focuses on national-level agricultural and, in cases, forest sector appraisal of the economic consequences of environmental outcomes and policy actions. He began this work by outlining the appropriate methodology to use in a synthesis paper and has applied it in groundbreaking unique work on ozone damages, acid rain, El Nino-Southern Oscillation forecasting, climate change effects, GHG mitigation, biofuel production/policy, bioelectricity, farm program revisions, and climate change adaptation. McCarl was lead economist on a USGCRP report, author of three IPCC reports, and author of a UNFCCC report on climate change adaptation cost and has generated a number of USDA, NOAA, and USEPA climate-related reports. McCarl received a B.S. in business statistics from the University of Colorado and Ph.D. in management science from Pennsylvania State University. He served on the National Academies Committee on America’s Climate Choices Panel on Limiting the Magnitude of Future Climate Change.

Peter Pfromm is a professor of chemical engineering and bioengineering at Washington State University. He worked for Membrane Technology and Research Inc. in Menlo Park, California before pursuing graduate studies. After graduate school, Pfromm joined the faculty of the Institute of Paper Science and Technology in Atlanta, Georgia and then the Department of Chemical Engineering at Kansas State University Current projects in his laboratory deal with ammonia synthesis using nitrides, and techno-economics of small-scale ammonia synthesis. He is a coinventor of four U.S. patents and has served on several expert panels assembled by the National Academies and the U.S. Department of Energy (DOE), notably coauthoring the DOE report “Sustainable Ammonia Synthesis.” Pfromm received an M.A. in process engineering from the University of Stuttgart, Germany, and a Ph.D. in chemical engineering from the University of Texas—Austin.

Jeffrey Silverstein is deputy administrator, Office of National Programs, Animal Production and Protection, USDA ARS since 2016, where he has broad oversight of the ARS intramural research program on food animals. With a team of national program leaders, he directs the programs and priorities of the Animal Production; Animal Health; Veterinary, Medical, and Urban Entomology; and Aquaculture research activities. Silverstein led ARS involvement in the Global Research Alliance on Agricultural Greenhouse Gases in 2017 and 2018, and his work with animal production and protection provides a broad overview of issues related to evaluating the environmental impact of animal products throughout their life cycle. Silverstein graduated from Colgate University with a B.A. in biology and East Asian Studies and received his Ph.D. from the University of Washington in fisheries/aquaculture genetics. He has authored or coauthored 83 refereed publications and abstracts, three book chapters, and 15 invited symposium papers and edited one book. His work has focused on genetics and disease in animal species, mostly fish.
