I am a Professor at American University with a joint appointment in the School of Public Affairs and the School of International Service. My research seeks to understand the cross-national causes and consequences of political violence. I have published numerous peer-reviewed articles across academic disciplines, including political science, economics, criminology, and international studies.

I also am a contributor and an editor for the blog, Political Violence @ a Glance.

Some of my research was supported by the National Consortium for the Study of Terrorism and Responses to Terrorism START, where I am an Investigator and Research Affiliate. I have current research supported by NCITE.
