history evolved to work on indicator mineral methods in mineral exploration, geological and geochemical mapping, regional groundwater investigations, shoreline erosion, natural hazards, and climate change programs. Dr. Thorleifson’s last two years in Canada were largely spent coordinating science and policy with respect to water-related issues in the Government of Canada system, with emphasis on groundwater. This work also involved planning coordination of the geological survey role with those of other departments and universities. Previously, he was also President of the Geological Association of Canada, and President of the Canadian Federation of Earth Sciences. He did his undergraduate studies at the University of Winnipeg, received his Masters at the University of Manitoba, and received his Ph.D. from the University of Colorado in Boulder.


Elizabeth A. Eide is the director of the Board on Earth Sciences and Resources at the NRC, a position she has held since spring 2012.

While in Norway her research included basic and applied projects related to isotope geochronology mineralogy and petrology, and crustal processes, with emphasis on both basic and applied research projects. Her publications include 45 journal articles and book chapters, and 10 Geological Survey reports. She completed a Ph.D. in geology at Stanford University and received a B.A. in geology from Franklin and Marshall College.

Jason R. Ortego is a research associate with the Board on Earth Sciences and Resources at the National Academies. He received a B.A. in English from Louisiana State University in 2004 and an M.A. in international affairs from George Washington University in 2008. He began working for the National Academies in 2008 with the Board on Energy and Environmental Systems, and in 2009 he joined the Board on Earth Sciences and Resources.

Peggy Tsai is a program officer with the Board on Agriculture and Natural Resources at the National Research Council (NRC). Since joining the board in 2004, she has worked on various studies in topics such as agricultural biotechnology, infectious diseases, food security and international agriculture. She served most recently as the study director for the Evaluation of a Site-Specific Risk Assessment for the Department of Homeland Security’s Planned National Bio- and Agro-Defense Facility in Manhattan, Kansas (2010). She began her work with the NRC as a Christine Mirzayan Science and Technology Policy Fellow. Peggy received an M.A. in Science, Technology, and Public Policy from George Washington University, and B.S. in microbiology and molecular genetics with a double major in political science from UCLA.
