He co-founded Princeton's Program on Science and Global Security and was founding co-chair of the International Panel on Fissile Materials from 2006-14. During 1993-4, he served as Assistant Director for National Security in the White House Office of Science and Technology Policy. In 1993, he received the MacArthur Foundation's "genius" award and, in 2010, the American Physical Society's Leo Szilard Award "for his outstanding work and leadership in using physics to illuminate public policy in the areas of nuclear arms control and nonproliferation, nuclear energy, and energy efficiency." He has worked on fissile material policy issues for over forty years.

Masafumi Takubo is a self-taught, Tokyo-based writer on nuclear-policy issues. He is a member the International Panel on Fissile Materials and a consultant for Princeton University's Program on Science and Global Security. He set up the Kakujoho.net (Nuclear Information) website in 2005 to provide Japanese policy makers, journalists and citizens, with timely, in-depth analysis and research tools related to nuclear issues. He publishes in several Japanese magazines, and taught a course on Peace Studies at Hosei University in Tokyo, Japan. Since 1975 he has worked with Gensuikin, the Japan Congress against Atomic and Hydrogen Bombs, in various capacities and helped organize numerous international conferences.
