Patrick Johnston is a PhD candidate in the Department of Political Science at Northwestern University and a CISAC predoctoral fellow. His dissertation, "Humanitarian Intervention and the Strategic Logic of Mass Atrocities in Civil Wars," asks why ethnic cleansing and genocidal violence frequently increase dramatically after international actors threaten to intervene militarily or deploy significant numbers of troops in coercive interventions. Johnston received a BA in history and a BA in political science, both with distinction, from the University of Minnesota, Morris and an MA in political science from Northwestern University.

Stephen J. Stedman joined CISAC in 1997 as a senior research scholar, and was named a senior fellow at FSI and CISAC and professor of political science (by courtesy) in 2002. He served as the center's acting co-director for the 2002-2003 academic year. Currently he directs the Ford Dorsey Program in International Policy Studies at Stanford and CISAC's Interschool Honors Program in International Security Studies. His current research addresses the future of international organizations and institutions, an area of study inspired by his recent work at the United Nations. In the fall of 2003 he was recruited to serve as the research director of the U.N. High-Level Panel on Threats, Challenges and Change. Upon completion of the panel's report, A More Secure World: Our Shared Responsibility, Annan asked Stedman to stay on at the U.N. as a special advisor with the rank of assistant secretary-general, to help gain worldwide support in implementing the panel's recommendations. Following the U.N. world leaders' summit in September 2005, during which more than 175 heads of state agreed upon a global security agenda developed from the panel's work, Stedman returned to CISAC. Before coming to Stanford, Stedman was an associate professor of African studies at the Johns Hopkins University School of Advanced International Studies in Washington, D.C. He has served as a consultant to the United Nations on issues of peacekeeping in civil war, light weapons proliferation and conflict in Africa, and preventive diplomacy.
