Michaela Mattes specializes in International Relations. Her research focuses on security institutions, in particular conflict management agreements and military alliances. She is interested in questions such as whether these agreements can constrain the behavior of international and domestic actors, through which mechanisms they work and under which conditions, and why they are designed the way they are. She has published articles in American Journal of Political Science, International Organization, Journal of Politics, International Studies Quarterly, and Conflict Management and Peace Science. She has also been involved in a large data collection effort on changes in leaders supporting coalitions funded by the NSF.
