Scott Sagan is a professor of political science and co-director of Stanford's Center for International Security and Cooperation. He is on sabbatical in 2008-09. Before joining the Stanford faculty, Sagan was a lecturer in the Department of Government at Harvard University and served as a special assistant to the director of the Organization of the Joint Chiefs of Staff in the Pentagon. He has also served as a consultant to the office of the Secretary of Defense and at the Sandia National Laboratory and the Los Alamos National Laboratory.

Sagan is the author of Moving Targets: Nuclear Strategy and National Security (Princeton University Press, 1989), The Limits of Safety: Organizations, Accidents, and Nuclear Weapons(Princeton University Press, 1993), and with co-author Kenneth N. Waltz, The Spread of Nuclear Weapons: A Debate Renewed (W.W. Norton, 2002). He is the co-editor of Peter R. Lavoy, Scott D. Sagan, and James L. Wirtz, Planning the Unthinkable (Cornell University Press, 2000). Sagan was the recipient of Stanford University's 1996 Hoagland Prize for Undergraduate Teaching and the 1998 Dean's Award for Distinguished Teaching. As part of CISAC's mission of training the next generation of security specialists he and Stephen Stedman founded Stanford's Interschool Honors Program in International Security Studies in 2000.

His recent articles include "How to Keep the Bomb From Iran," in Foreign Affairs (September-October 2006); "The Madman Nuclear Alert: Secrecy, Signaling, and Safety in October 1969" co-written by Jeremi Suri and published in International Security in spring 2003; and "The Problem of Redundancy Problem: Will More Nuclear Security Forces Produce More Nuclear Security?" published in Risk Analysis in 2004. The first piece warns against "proliferation fatalism" and "deterrence optimism" to argue that the United States should work to prevent Iran's pursuit of nuclear weapons by addressing the security concerns that are likely motivators for Iran's nuclear ambitions. The International Security piece looks into the events surrounding a secret nuclear alert ordered by President Nixon to determine how effective the alert was at achieving the president's goal of forcing negotiations for the end of the Vietnam War. It also questions many of the assumptions made about nuclear signaling and discusses the dangers of new nuclear powers using this technique. Sagan's article on redundancy in Risk Analysis won Columbia University's Institute for War and Peace Studies 2003 Best Paper in Political Violence prize. In this article, Sagan looks at how we should think about nuclear security and the emerging terrorist threat, specifically whether more nuclear facility security personnel increases our safety. His article, "Realism, Ethics, and Weapons of Mass Destruction" appears in Ethics and Weapons of Mass Destruction: Religious and Secular Perspectives, edited by Sohail Hashmi and Steven Lee. In addition to these works, Sagan is also finishing a collection of essays for a book tentatively entitled Inside Nuclear South Asia.
