Brent Durbin (discussant) is completing his PhD in political science at the University of California, Berkeley, and is a predoctoral fellow at CISAC and a dissertation fellow at the Institute on Global Conflict and Cooperation. His dissertation, "Changing the Guard: How U.S. Intelligence Adapts to New Threats and Opportunities," explains the policy processes governing how U.S. intelligence agencies respond to major changes in the international threat environment. More broadly, Durbin's research focuses on the micro- and macro-level organizational dynamics of national security bureaucracies. Durbin has previously held research fellowships at The George Washington University's Elliott School of International Affairs, and at the University of Cambridge (U.K.). Prior to attending Berkeley, he served as press secretary for U.S. Senator Patty Murray, and worked as an advisor and senior staff member on several campaigns for U.S. Congress. He graduated magna cum laude from Oberlin College with a BA in politics and English literature. He also holds an MPP from Harvard University's John F. Kennedy School of Government, and an MA in political science from the University of California, Berkeley.

Nuclear forensics is the analysis of nuclear materials recovered from either the capture of unused nuclear materials, or from the radioactive debris following a nuclear explosion. The APS/AAAS Working Group report, which will be reviewed in this seminar, provides an appraisal of the state of the art of nuclear forensics; an assessment of its potential for preventing and identifying unattributed nuclear attacks; and identifies the policies, resources and human talent to fulfill that potential. The intended audience is the Congress, U.S. government agencies and other institutions involved in nuclear forensics as well as interested scientists.
