I’m an Associate Professor in the Department of Political Science and Director of the Political Violence FieldLab at Yale University. I’m also a faculty associate of Yale’s Institution for Social and Policy Studies (ISPS), Jackson Institute for Global Affairs, and MacMillan Center for International and Area Studies. I served as Technical Adviser for USAID’s Measuring the Impact of Stabilization Initiatives (MISTI) project in Afghanistan for 2012-15.
My research focuses on violence and its effects in both conventional and guerrilla wars, with emphasis on Afghanistan and Russia’s Northern Caucasus (particularly Chechnya). My work draws on diverse methods, ranging from historical and cross-national comparisons to field, survey and “natural” experiments. I am currently working on three projects: the sources of military effectiveness in conventional wars since 1800; how development assistance and violence affect public attitudes and insurgent behavior in Afghanistan; and the effectiveness of airpower in “small wars.” I have conducted fieldwork in Afghanistan and Russia.
My research has been published in the American Political Science Review, American Journal of Political Science, Foreign Affairs, International Organization, Journal of Conflict Resolution, Journal of Peace Research, Journal of Politics, and World Politics, among others. My Google Scholar page is here. My research has been funded by AidData/USAID, the Air Force Office of Scientific Research, the MacArthur Foundation, and the United States Institute of Peace. I have received the 2013 Pi Sigma Alpha Award; 2009 Kellogg-Notre Dame Award; the 2007 APSA Helen Dwight Reid Prize for Best Dissertation in International Relations, Law, and Politics; and the 2007 Stanley Kelley Jr. Prize for Teaching Excellence in Princeton University’s Politics Department. I also blog occasionally at The Monkey Cage and Political Violence@a Glance.
