I am an Associate Professor in the School of Foreign Service and the Director of the Mortara Center for International Studies, as well as a core faculty member in the Security Studies Program at Georgetown University.  Previously, I was an Associate Professor in the Department of Political Science at George Washington University.

My research and teaching interests focus on the domestic politics of international relations and US foreign policy, especially the role of leaders, the presidency, and the politics of using force.  My book, Leaders at War: How Presidents Shape Military Interventions, was published by Cornell University Press in 2011, and received the 2012 Jervis-Schroeder Best Book Award from APSA’s International History and Politics section.  My work has been published or is forthcoming in the Annual Review of Political Science, International OrganizationInternational Security, World Politics, International Studies Quarterly, Security Studies, the Journal of Conflict Resolution,  the American Journal of Political Science, International Studies Review, and Foreign Affairs. 

I recently completed my second book manuscript, The Insiders’ Game: Elites, Democracy, and War (under advanced contract with Princeton University Press).  The book argues that elites, rather than voters, are the main audience for foreign policy decisions in democraciesMy research also examines other aspects of the politics of foreign policy, including how leaders interact with advisers, the role of diplomacy in US foreign policy, and the domestic politics of nuclear choices.

I am an editor and contributor to the Washington Post Monkey Cage blog, and a non-resident senior fellow at the Brookings Institution.
