Holdren is the Director of the Woods Hole Research Center as well as Teresa and John Heinz Professor of Environmental Policy and Director of the Program on Science, Technology, and Public Policy at the Kennedy School of Government, Harvard University. He is also Professor of Environmental Science and Policy in Harvard's Department of Earth and Planetary Sciences and the current president of AAAS. Dr. Holdren was educated at the Massachusetts Institute of Technology and Stanford University in aeronautics/astronautics (fluid dynamics) and theoretical plasma physics, receiving his Ph.D. degree in 1970. After brief stints at the Livermore Laboratory and the California Institute of Technology, he co-founded in 1973 and co-led until 1996 the campus-wide, interdisciplinary, graduate-degree program in energy and resources at the University of California-Berkeley—the Energy and Resources Group (ERG). His work has focused on causes and consequences of global environmental change, fusion science and technology, comparative analysis of energy options, ways to reduce the dangers from nuclear weapons and materials, and the interaction of content and process in science and technology policy. Dr. Holdren is a member of the National Academy of Sciences, the National Academy of Engineering, the American Academy of Arts and Sciences, and the Council on Foreign Relations. From 1993 through 2004 he served as Chair of the Committee on International Security and Arms Control of the National Academy of Sciences, and from 1994 to 2001 he was a member of President Clinton's Committee of Advisors on Science and Technology. Since 2002 he has been Co-Chair of the independent, bipartisan National Commission on Energy Policy. He has been the recipient of a MacArthur Prize Fellowship (1981 to 1986), the Volvo Environment Prize (1993), the Tyler Prize for Environment (2000), and the John Heinz Prize for Public Policy (2001), among other awards. In 1995, he gave the acceptance speech for the Nobel Peace Prize on behalf of the Pugwash Conference on Science and World Affairs (which he served as Chair of the Executive Committee from 1987 to 1997).
