I am an Associate Professor of International Studies at the Hamilton Lugar School of Global and International Studies, Indiana University-Bloomington. I am also nonresident senior advisor (and former distinguished visiting fellow) at the Perry World House, University of Pennsylvania.

My areas of research are in international relations and political theory, with particular focus on topics in modern Iranian politics, US-Iran relations, diplomacy, liberal political thought, and democratic theory. I am the co-editor-in-chief of International Studies Review, the flagship review journal of the International Studies Association.

I am also passionate about gardening and landscape design. I combine my thoughts on politics, culture, international affairs, and gardening in the newsletter Hedge of State.
