I am an Assistant Professor in the Department of Political Science at the University of Massachusetts Boston.
I research terrorism, civil and international conflict, protest, and state repression. I also research signaling and reputation in cyber conflict.
My book, Force of Words: The Logic of Terrorist Threats (Columbia University Press 2020) is a detailed study of how terrorist groups use threats to achieve their political aims.
I completed my Ph.D. at Columbia University. I have conducted fieldwork in Northern Ireland, Spain, Sri Lanka and Peru, interviewing members of the Irish Republican Army, ETA, the Tamil Tigers, Shining Path, and the Túpac Amaru Revolutionary Movement.
My research has been supported by the Horowitz Foundation for Social Policy, the Earth Institute, and the Global Public Policy Network.
