I am 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 International OrganizationInternational Security, International Studies Quarterly, Security Studies, the American Journal of Political Science, and International Studies Review. 

I am currently working on my second book manuscript, The Insiders’ Game: Elites, Democracies, and War, which argues that elites, rather than voters, are the main audience for foreign policy decisions in democraciesAn article drawn from the book project was published in Security Studies.  My current 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 politics of arms control.

I am an editor and contributor to the Washington Post Monkey Cage blog, and a non-resident senior fellow at the Brookings Institution. In 2016, I was a Visiting Fellow at the Council on Foreign Relations, where I was previously a Stanton Nuclear Security Fellow.  I have held fellowships at the Woodrow Wilson International Center for Scholars, the John M. Olin Institute for Strategic Studies at Harvard University, and the Brookings Institution.
