My interests revolve mainly around issues of violent armed conflict and its resolution. My work covers a range of issues such as the militarization of societies, determinants of human rights violations, negotiations in international conflict resolution, interventions into civil wars, and most recently climate change.
I have published articles in the Journal of Politics, Journal of Conflict Resolution, Political Research Quarterly, International Interactions, International Studies Quarterly, and the Journal of Peace Research, among others. I am also the author of Civil Wars and Foreign Powers (University of Michigan Press, 2000), Organizing Societies for War (Praeger Press, 1994), and Sixteen Million One (Paradigm, 2009), which is a book on the causes, consequences, and possible solutions to civil wars.
My research has been funded by the National Science Foundation, the World Bank, and the Politicial Instability Task Force. I am on the editorial boards of International Interactions and Conflict Management and Peace Science, and have been an associate editor of the Journal of Peace Research. I am also co-editor of a book series on civil wars by Routledge Press.
I teach courses in international relations on topics such as: International Conflict, Conflict Management, Civil Wars, and climate change and conflict.
I have held teaching positions at the University of Canterbury (New Zealand) and Binghamton University. I spent a year as a Fulbright Scholar at the Peace Research Institute, Oslo (PRIO).
