I am an Associate Professor of International Affairs, Johns Hopkins University School of Advanced International Studies (SAIS). I was born in L'viv (USSR, current-day Western Ukraine) and grew up in Israel. I received a BA in Political Science and International Relations at the Hebrew University of Jerusalem and a PhD at the University of Wisconsin-Madison.

My research focuses on how individuals, institutions and societies respond to extreme situations: violence, state collapse, and rapid change. 
My first book, Ordinary Jews: Choice and Survival during the Holocaust (Princeton University Press, 2017) analyzes how Soviet and Polish Jews chose their survival strategies under the Nazi occupation. My second book, Reform and Rebellion in Weak States (Cambridge University Press, 2020) co-authored with Scott Gehlbach uses economic theory and historical case studies to explain why in weak states reforms often provoke rebellion. 
My articles have appeared in the American Political Science Review, Journal of Politics, Comparative Political Studies, Comparative PoliticsEast European Politics and SocietiesSlavic Review, Democratization and several other journals and edited volumes. 

Additionally, I am the lead editor of the American Political Science Association Comparative Politics Newsletter
