I am an Associate Professor in the Department of Politics at the University of Virginia. My ongoing research explores the influence of domestic politics on foreign policy and international relations. I also conduct research in the area of international terrorism and am a principal investigator for a Department of Defense Minerva Initiative project to map and analyze collaborative relationships between terrorist organizations. I have recently published articles in International Organization, Journal of Politics, International Studies Quarterly, The Journal of Conflict Resolution, and the Annual Review of Political Science. My book, War and Democratic Constraint(with Matthew Baum), is now available from Princeton University Press. I have been a fellow at Harvard University and the University of Pennsylvania and holds degrees from UCLA and McGill University.
