David Holloway is the Raymond A. Spruance Emeritus Professor in International History at Stanford University. At Stanford, Holloway has served as Chair of the International Relations Program, co-director of the Center for International Security and Cooperation, Associate Dean in the School of Humanities and Sciences, and director of the Freeman-Spogli Institute for International Studies. Holloway’s research during the Cold War focused on East-West relations with particular reference to nuclear weapons.  Since then he has devoted more attention to the international history of nuclear weapons.  He has written on the history and sociology of science in the Soviet Union.  He has also worked on technical and policy issues related to national security policy.  His Stalin and the Bomb: the Soviet Union and Atomic Energy 1939-1956 (Yale University Press, 1994) won the Vucinich and Shulman prizes of the American Association for the Advancement of Slavic Studies and was selected by the New York Times as one of the 11 best books of 1994. His current research deals with the international history of nuclear weapons.

Margaret E. Kosal is an Associate Professor at the Sam Nunn School of International Affairs at Georgia Tech. Her research explores the relationships among technology, strategy, and governance. Her research focuses on two, often intersecting, areas: reducing the threat of weapons of mass destruction and understanding the role of emerging technologies for security. Her work aims to understand and explain the role of technology and technological diffusion for national security at strategic and operational levels. In the changing post-Cold War environment, the most advanced military power no longer guarantees national or international security in a globalized world in which an increasing number of nation-states and non-state actors have access to new and potentially devastating dual-use capabilities. The long-term goals of her work are to understand the underlying drivers of technological innovation and how technology affects national security and modern warfare. She is interested in both the scholarly, theoretical level discourse and in the development of new strategic approaches and executable policy options to enable US dominance and to limit the proliferation of unconventional weapons.

Hans M. Kristensen is Director of the Nuclear Information Project at the Federation of American Scientists where he provides the public with analysis and background information about the status of nuclear forces and the role of nuclear weapons. He specializes in using the Freedom of Information Act (FOIA) in his research and is a frequent consultant to and is widely referenced in the news media on the role and status of nuclear weapons. His collaboration with researchers at NRDC in 2010 resulted in an estimate of the size of the U.S. nuclear weapons stockpile that was only 13 weapons off the actual number declassified by the U.S. government. Kristensen is co-author of the Nuclear Notebook column in the Bulletin of the Atomic Scientists and the World Nuclear Forces overview in the SIPRI Yearbook. The Nuclear Notebook is, according to the publisher, “widely regarded as the most accurate source of information on nuclear weapons and weapons facilities available to the public. 

Frederick Lamb is a Research Professor of Physics, a core faculty member in the Program on Arms Control, Disarmament, and International Security, and Brand and Monica Fortner Endowed Chair of Theoretical Astrophysics Emeritus. He has made seminal contributions to atomic physics and high-energy and relativistic astrophysics, and has played important roles in addressing a variety of national security challenges. Professor Lamb it the former co-chair of the American Physical Society’s Study Group on Boost-Phase Intercept for National Missile Defense, an astrophysicist, and an expert on nuclear test ban verification and ballistic missile defense. Lamb has given numerous public lectures, lectures at universities and defense and public policy institutes, and briefings to congressional committees, and is a founding member of the new APS-sponsored Physicists Coalition for Reducing the Nuclear Threat. In 2005, Lamb shared the Leo Szilard Award of the American Physical Society for his leadership of the 2003 APS study of boost-phase missile defense.
