I am a Professor of Politics and International Affairs at the Princeton School of Public and International Affairs and the Politics Department at Princeton University. I joined the Princeton faculty in 2003 after receiving my PhD in Political Science from UC Berkeley. I am co-director of the Princeton Workshop on Post-Communist Politics.

My main current research interests are in comparative political behavior with a focus on authoritarian and post-authoritarian regimes (largely in Eastern Europe and the former Soviet Union). I have also worked on comparative and international political economy of Eastern Europe and Latin America, and on democratization and democratic backsliding, with a focus on the role of electoral behavior and political parties.

My first book, entitled "From Economic Crisis to Reform: IMF Programs in Latin America and Eastern Europe" was published by Princeton University Press in February 2009. My second book, "Communism's Shadow: Historical Legacies and Contemporary Political Attitudes" (joint with Joshua A. Tucker), was published in 2017 by Princeton University Press. My work has also appeared in a variety of academic journals, including The American Journal of Political Science, The Journal of Politics, World Politics, Comparative Political Studies, Comparative Politics, Quarterly Journal of Political Science, International Studies Quarterly, Journal of Democracy, Studies in Comparative International Development, and East European Politics and Societies.
