Profile
Biography
My research focuses mostly on organizational dynamics of terrorism, civil conflict, and crime. You can find my work in the Journal of Politics, Comparative Political Studies, the Journal of Conflict Resolution, and other journals. My co-authored book "Insurgent Terrorism: Intergroup Relationships and the Killing of Civilians" was published by Oxford University Press. Currently I am one of the co-Principal Investigators on the ESRC-funded Multilingualism, Conflict, and Conflict Resolution in Africa () project. I am also writing a book manuscript with Hyeran Jo on terrorist designation, and editing the book What Do We Know About Terrorism? (Bloomsbury) with an excellent group of authors. I am an Associate Editor of Terrorism and Political Violence and on the editorial board of Perspectives on Terrorism. Previously I served a five-year term as Associate Editor of International Studies Quarterly. Projects I have worked on have been funded by the US National Science Foundation and the Mexican Presidency. My research has been discussed in The New York Times, El PaÃs, The Guardian, and other outlets. Before university, I was enlisted in the U.S. Marine Corps infantry for four years. If you are interested in doing a PhD under my supervision, see .
