Dr. Peter Blair, executive director of the NRC Division on Engineering and Physical Sciences, was also director of the National Academies’ series of studies, America’s Energy Future: Technology and Transformation (2006 to 2011), requested by Congress to inform the national debate about the role of science and technology in shaping the nation’s energy future. Prior to his current position, he was executive director of Sigma Xi, the Scientific Research Society and publisher of American Scientist (1997–2001). He was previously assistant director of the of the Congressional Office of Technology Assessment (OTA) and director of its Division of Industry, Commerce, and International Security and, before that, OTA’s energy policy and research program manager. He received the agency’s distinguished service award in 1991. Dr. Blair was cofounder and principal of Technecon Analytic Research, Inc., which was acquired by the Reading Energy Corporation in 1985. In the 1970s and 1980s he served on the faculty of the University of Pennsylvania and in the 1990s as an adjunct faculty member at the University of North Carolina at Chapel Hill. 

Dr. Blair is the author or co-author of Multiobjective Regional Energy Planning (1978), Geothermal Investment Decision Analysis (1982), and Input-Output Analysis: Foundations and Extensions (1st ed., 1985; 2nd ed., 2010), and Congress’s Own Think Tank: Learning from the Legacy of the Congressional Office of Technology Assessment, 1972–1995 (2013); and he co-edited Trends in Industrial Innovation: Industry Perspectives & Policy Implications (1997). He has authored over a hundred technical articles on energy and environmental policy, electric power systems, operations research, economics and regional science, and science policy.

Dr. Blair is a fellow of the American Association for the Advancement of Science (AAAS) and chaired its section on Societal Impacts of Science and Engineering. He currently serves on the National Renewable Energy Technology Analysis Advisory Committee. He is a past co-chair of the National Science Foundation’s Business and Operations Advisory Committee and a former member of the Board of Directors for the National Institute for the Statistical Sciences and advisory or visiting committees for Carnegie Mellon University’s Engineering and Public Policy Department, the Colorado School of Mines, Electric Power Research Institute, Gas Research Institute, Lawrence Livermore Laboratory’s Energy and Environment Division, Lawrence Berkeley Laboratory’s Energy Division, New York Energy Research and Development Authority, Houston Applied Research Center, and many others. He has served on the editorial board of IEEE Spectrum and as an associate editor of the Journal of Regional Science.

Dr. Blair holds a BS in engineering from Swarthmore College, and graduate degrees from the University of Pennsylvania: an MSE in systems engineering, and MS and PhD in energy management and policy.



Scott T. Weidman is the Deputy Executive Director for Science and Engineering for the Division on Engineering and Physical Sciences. Prior to this he served as Director of the Board on Mathematical Sciences and Their Applications for 18 years. During his 27 years at the Academies he has worked with that board and the Board on Chemical Sciences and Technology, and has directed the units that perform annual peer reviews of the Army Research Laboratory and the National Institute of Standards and Technology. His Academies activities have spanned a wide variety of topics related to mathematical, chemical, and materials sciences; laboratory assessment; and science and technology policy. He holds bachelor degrees in mathematics and materials science from Northwestern University and an M.S. and Ph.D. in applied mathematics at the University of Virginia. Before joining NRC, he held positions with General Electric, General Accident Insurance Company, Exxon Research and Engineering, and MRJ, Inc.
