I hold a PhD and MA in political science from the University of Washington, Seattle, and I have a BA in journalism and political science from Indiana University, Bloomington.
Prior to joining UCL, I was a post-doctoral research fellow at Harvard University, at the Belfer Center for Science and International Affairs, and an Assistant Professor in political science at Leiden University. I have also been a Research Associate at the Peace Research Institute, Oslo.
I am an Associate Editor at Journal of Peace Research, serve on the international advisory board of Nations and Nationalism, am a member of the management committee of the European Network of Conflict Research, and sit on the council of the British Conflict Research Society.
My publications focus on political violence. I'm interested in why some states are better able to avoid conflicts within their borders than others, how institutions can (or cannot) promote intrastate peace, the influence of foreign fighters, the dynamics within self-determination movements, and post-war state-building.
