Scott D. Sagan

Scott D. Sagan is the Caroline S.G. Munro Professor of Political Science at Stanford University and a Senior Fellow at the Freeman Spogli Institute for International Studies. He serves as Co-Director of the Center for International Security and Cooperation (CISAC) and holds the position of Bass University Fellow in Undergraduate Education. Sagan also co-chairs the American Academy of Arts and Sciences' Committee on International Security Studies, demonstrating his significant influence in the field of international security.

Sagan received his Ph.D. in Political Science from Harvard University in 1983 and his B.A. in Government from Oberlin College in 1977. Prior to joining Stanford, he taught at Harvard University and served as special assistant to the director of the Organization of the Joint Chiefs of Staff in the Pentagon, providing him with valuable practical experience in defense policy.

Professor Sagan's research primarily focuses on nuclear weapons policy, international security, arms control, and nonproliferation. His work examines the organizational, political, and ethical dimensions of nuclear strategy, with particular attention to the risks of nuclear accidents, the effectiveness of nonproliferation policies, and public attitudes toward nuclear weapons use. He has pioneered important theoretical frameworks regarding the organizational causes of nuclear accidents and the normative constraints on nuclear weapons use.

Sagan's publications reveal a consistent focus on nuclear deterrence theory, the organizational aspects of nuclear command and control, and the ethical dimensions of nuclear weapons policy. His work bridges theoretical analysis with practical policy implications, often challenging conventional wisdom about nuclear strategy and proliferation. Recent publications show increasing attention to public opinion on nuclear weapons use, the evolving nature of nuclear deterrence in the contemporary security environment, and the relationship between international law and nuclear strategy.
