Founding coordinator of the Nuclear Proliferation Prevention Project (NPPP), and Associate Professor at the LBJ School of Public Affairs, University of Texas at Austin. He has worked since 1987 on reducing the proliferation and terrorism risks associated with civilian nuclear applications, in various capacities in the U.S. Congress, the Nuclear Control Institute, Greenpeace, and academia. His accomplishments include co-authoring a 1987 investigative report that led Congress to ban air shipment of civilian plutonium over the United States; drafting a provision of the U.S. Energy Policy Act of 1992 (the “Schumer Amendment”) that sharply restricted exports of bomb-grade uranium; advocating successfully in 1993 for the U.S. government to cancel a proposed nuclear reactor slated to use bomb-grade fuel; intervening successfully in 2001 before the U.S. Nuclear Regulatory Commission (NRC) to block a proposed export of bomb-grade uranium to Belgium; and intervening successfully in 2006 before the NRC to restore public disclosure of proposed exports of bomb-grade nuclear materials. Kuperman has made invited presentations to the International Atomic Energy Agency, the U.S. Nuclear Regulatory Commission, the U.S. Congress, the Department of Energy, and the National Academy of Sciences. His publications include a 2006 cover story in the Bulletin of the Atomic Scientists. He holds an A.B. in Physical Sciences from Harvard University, an M.A. in International Relations and International Economics from the Johns Hopkins University School of Advanced International Studies (SAIS), and a Ph.D. in Political Science from the Massachusetts Institute of Technology.
