Christopher Blattman is currently completing a PhD in economics at UC Berkeley and holds a master's degree from Harvard's Kennedy School of Government. His research focuses on the causes and consequences of conflict and violence, the organization of guerrilla groups, as well as what post-conflict development policies work, for whom, and why. He recently completed a survey of war-affected men and boys in northern Uganda, and is presently conducting a similar survey of women and girls. Two randomized evaluations of post-conflict programs are planned in the same region for 2007, one studying the role of a group-based economic intervention in promoting community reintegration of ex-combatants, and another studying the introduction of a government and an independent press into communities not currently served by newspapers.

James Fearon is the Theodore and Frances Geballe Professor in the School of Humanities and Sciences, a professor of political science and CISAC affiliated faculty member at Stanford University. His research has focused on democracy and international disputes, explanations for interstate wars, and, most recently, the causes of civil and especially ethnic violence. He is presently working on a book manuscript (with David Laitin) on civil war since 1945. Representative publications include "Neotrusteeship and the Problem of Weak States" (International Security, Spring 2004), "Ethnicity, Insurgency, and Civil War" (APSR, February 2003), and "Rationalist Explanations for War" (International Organization, Summer 1995). Fearon won the 1999 Karl Deutsch Award, which is "presented annually to a scholar under the age of forty, or within ten years of the acquisition of his or her doctoral degree, who is judged to have made, through a body publications, the most significant contribution to the study of international relations and peace research." He was elected as a fellow of the American Academy of the Arts and Sciences in 2002.

Dara Kay Cohen is a PhD candidate in political science at Stanford University and was a fellow and research assistant at CISAC in 2004-2005 and 2005-2006. Her research at CISAC involved studying the politics of national security; she examined the creation of the Department of Homeland Security, how security issues have affected congressional elections and co-wrote a paper with Jacob N. Shapiro on the failure of the homeland security alert system. Her current dissertation research focuses on the use of sexual violence during civil wars, and she spend last summer in Sierra Leone conducting initial field work. She previously worked at the Department of Justice as a paralegal in the Outstanding Scholars Program in the Counterterrorism Section and at the u.S. Embassy in London on terrorist financing issues.

Mariano-Florentino Cuéllar, with a PhD in political science from Stanford as well as a law degree from Yale, focuses his scholarship on how organizations cope with the legal responsibility for managing complex criminal justice, regulatory, and international security problems. He has published the leading academic paper on the operation of federal money laundering laws, and one of the most exhaustive empirical case studies of public participation in regulatory rulemaking proceedings. Recent projects address the role of criminal enforcement in managing transnational threats, the physical safety of refugee communities in the developing world, legislative and budgetary dynamics affecting the federal Department of Homeland Security, and the impact of bureaucratic structure on how institutions implement legal mandates. Professor Cuéllar is an affiliated faculty member at the Stanford Center for International Security and Cooperation, and a member of the Executive committee for the Stanford International Initiative. Before joining the Stanford Law School faculty in 2001, he served as senior advisor to the u.S. Treasury Department's Undersecretary for Enforcement and clerked for Chief Judge Mary M. Schroeder of the U.S. Court of Appeals for the Ninth Circuit.

Nuclear fuel supply assurance is a long-term issue that has been studied in various venues since the beginning of the nuclear area. This topic has recently gained greater urgency with various countries now embarking on their own nuclear power programs and considering construction of their own fuel cycle facilities, including enrichment plants, to provide for their own fuel. Some of these fuel facilities could however be diverted for weapons material production within clandestine military programs. In this context the assured provision of internationally supplied nuclear fuel and fuel supply guarantees are meant to discourage new nuclear countries from developing domestic sensitive fuel cycle facilities. An IAEA initiative on this topic has culminated in a September 2006 IAEA Special Event Seminar held in conjunction with the 50th General Conference. Eleven different proposals for instituting fuel supply assurance arrangements were presented (some prior to and some during) the meeting. Noted among them was the NTI proposal that included a commitment from Warren Buffet to contribute 50 Million Dollars towards the purchase of a Uranium stockpile that would form the basis of a Nuclear Fuel Bank to be managed by the IAEA.

In this presentation I will review and comment on the recent supply assurance proposals made. I will discuss technical and institutional issues I have raised in reviewing these proposals, and I will rank all the proposals based on their ease of implementation and contribution to nonproliferation.

He also co-authored two chapters in the CISAC book , U.S. Nuclear Weapons Policy: Confronting Today's Threats, made numerous technical presentations, and was instrumental in bringing to CISAC the research project on U.N. Security Council Resolution 1540.

Bioterrorism is a growing threat. While the U.S. government has spent considerable sums on programs designed to protect the United States from a biological attack, no clear strategy has been articulated to guide planning and expenditures. This talk will present the outlines of a coherent strategy for coping with bioterrorism that includes diplomacy, deterrence and defense, with the emphasis on defense.

Dean Wilkening directs the Science Program at CISAC. He holds a Ph.D. in physics from Harvard University and spent 13 years at the RAND Corporation prior to coming to Stanford in 1996. His major research interests have been nuclear strategy and policy, arms control, the proliferation of nuclear, biological, and chemical weapons, ballistic missile defense, and conventional force modernization. His most recent research focuses on ballistic missile defense and biological terrorism. His work on missile defense focuses on the broad strategic and political implications of deploying national and theater missile defenses, in particular, the impact of theater missile defense in Northeast Asia, and the technical feasibility of boost-phase interceptors for national and theater missile defense. His work on biological weapons focuses on understanding the scientific and technical uncertainties associated with predicting the outcome of hypothetical airborne biological weapon attacks, with the aim of devising more effective civil defenses, and a reanalysis of the accidental anthrax release in 1979 from a Russian military compound in Sverdlovsk with the aim of improving our understanding of the human effects of inhalation anthrax.
