Tom's career spans more than two decades with the Department of Energy including managing policies and programs on the advancement of nuclear power and issues associate with security, waste management, and public trust.  He has degrees in Engineering, Applied Physics, and Chemical Engineering from Harvard University and the University of Pennsylvania.

Michael May is Professor Emeritus (Research) in the Stanford University School of Engineering and a senior fellow with the Institute for International Studies at Stanford University. He is the former co-director of Stanford University's Center for International Security and Cooperation, having served seven years in that capacity through January 2000. May is a director emeritus of the Lawrence Livermore National Laboratory, where he worked from 1952 to 1988, with some brief periods away from the Laboratory. While there, he held a variety of research and development positions, serving as director of the Laboratory from 1965 to 1971. May was a technical adviser to the Threshold Test Ban Treaty negotiating team; a member of the U.S. delegation to the Strategic Arms Limitation Talks; and at various times has been a member of the Defense Science Board, the General Advisory Committee to the AEC, the Secretary of Energy Advisory Board, the RAND Corporation Board of Trustees, and the Committee on International Security and Arms Control of the National Academy of Sciences. He is a member of the Council on Foreign Relations and the Pacific Council on International Policy, and a Fellow of the American Physical Society and the American Association for the Advancement of Science. May received the Distinguished Public Service and Distinguished Civilian Service Medals from the Department of Defense, and the Ernest Orlando Lawrence Award from the Atomic Energy Commission, as well as other awards. His current research interests are in the area of nuclear and terrorism, energy, security and environment, and the relation of nuclear weapons and foreign policy.

Lynn Eden is acting co-director (2008-09) at the Center for International Security and Cooperation, Freeman Spogli Institute for International Studies, Stanford University. Eden received her Ph.D. in sociology from the University of Michigan, held several pre- and post-doctoral fellowships, and taught in the history department at Carnegie Mellon before coming to Stanford. In the area of international security, Eden has focused on U.S. foreign and military policy, arms control, the social construction of science and technology, and organizational issues regarding nuclear policy and homeland security. She co-edited, with Steven E. Miller, Nuclear Arguments: Understanding the Strategic Nuclear Arms and Arms Control Debates (Ithaca, N.Y.: Cornell University Press, 1989). She was an editor of The Oxford Companion to American Military History (New York: Oxford University Press, 2000), which takes a social and cultural perspective on war and peace in U.S. history. That volume was chosen as a Main Selection of the History Book Club.

Eden's book Whole World on Fire: Organizations, Knowledge, and Nuclear Weapons Devastation(Ithaca: Cornell University Press, 2004; New Delhi: Manas Publications, 2004) explores how and why the U.S. government--from World War II to the present--has greatly underestimated the damage caused by nuclear weapons by failing to predict damage from firestorms. It shows how well-funded and highly professional organizations, by focusing on what they do well and systematically excluding what they don't, may build a poor representation of the world--a self-reinforcing fallacy that can have serious consequences, from the sinking of the Titanic to not predicting the vulnerability of the World Trade Center to burning jet fuel. Whole World on Fire won the American Sociological Association's 2004 Robert K. Merton Award for best book in science, knowledge, and technology.

Eden has also written on life in small-town America. Her first book, Crisis in Watertown (Ann Arbor: University of Michigan Press, 1972) was her college senior thesis; it was a finalist for a National Book Award in 1973. Her second book, Witness in Philadelphia, with Florence Mars (Baton Rouge: Louisiana State University Press, 1977), about the murders of civil rights workers Schwerner, Chaney, and Goodman in the summer of 1964, was a Book of the Month Club Alternate Selection.

Providing commentary on Dr. Eden's paper is Lieutenant Colonel John Vitacca, a national defense fellow for 2009-2010 at CISAC. 

John holds a Bachelor of Business Administration degree in Marketing from Texas A&M University, a Master of Business Administration degree in Management from Rensselaer Polytechnic Institute, and a Master of Arts degree in Military Operational Art and Science from Air Command and Staff College, Air University, Alabama.  He is a command pilot with over 3,400 flight hours in the B-2 and B-52, qualified as both an instructor and evaluator pilot.  Prior to coming to CISAC, John served in various assignments including a tour at the Pentagon as the Chief of the Global Persistent Attack Branch and the B-2/Next Generation Bomber subject matter expert.   Most recently, he was the Commander of the 393d Bomb Squadron at Whiteman Air Force Base, one of only two operational B-2 stealth bomber squadrons in the USAF.  His research at CISAC will focus on nuclear weapons policy issues.

Abstract
If an armed group cannot be defeated in war, are there conditions in peace that will allow for its demobilization and disbandment?  What are the key barriers that stand in the way?  Using case studies of the three large paramilitary organizations in Northern Ireland since the 1994 ceasefires, I weigh competing arguments from the civil conflict literature about the security concerns of previously warring parties that stand in the way of security normalization.  I find that existing theories miss two crucial forms of post-conflict security crises: intra-community criminality and inter-communal confrontations.  These two kinds of security concerns present two major challenges to the normalization of security that are instructive to broader theory on conflict termination and peace-building.  First, these security concerns are not the kind that outside actors can successfully manage without the partnership of local power brokers.  As a result, state actors institutionalize paramilitary authority rather than replacing it.  Second, the management of these security concerns does not present clear-cut opportunities for signaling the commitment to peace necessary for trust-building amongst formerly warring parties.  Armed groups are forced to make impossible choices that signal weak commitments and make a return to war more likely.

Brenna Marea Powell is a 6th year PhD candidate in the department of Government at Harvard University, and a doctoral fellow at the Multidisciplinary Program on Inequality and Social Policy at the Kennedy School of Government. She received her AB from Stanford in Comparative Studies in Race and Ethnicity. Her research interests include inequality, civil conflict and political violence in divided societies. Her three-article dissertation research explores the role of political institutions in redefining ethno-racial boundaries and social hierarchy. This includes work on post-conflict policing in Northern Ireland, racial policy in Brazil, and the politics of ethno-racial classification in the United States.
