I am an Assistant Professor of Public Policy and Political Science (by courtesy) at the University of Michigan. I specialize in comparative politics and international relations, with a focus on political violence, conflict, radicalization and extremism.

My current research examines the behavior of Islamic State supporters on social media. Specifically, I study how supporters respond to experiences of anti-Muslim hostility in the West (invited to revise and resubmit at the American Political Science Review), how they react to online propaganda, and whether they are sensitive to counter-extremism programs aiming to reduce radicalization. These projects draw on new data on the online behavior of over a million users linked to the Islamic State on Twitter, which I will soon make available for other researchers to use. My other projects examine the effect of war on pro-social behavior (published in the Journal of Economic Perspectives), the impact of terrorism on the dissemination of right-wing ideology in popular media (forthcoming in International Organization), and the link between security threats and citizens’ attitudes towards immigration.

I hold M.A., M.Phil., and Ph.D.  in Political Science from Columbia University and a B.A., summa cum laude, in Politics with Highest Honors from New York University.
