I am a  Senior Research Fellow in the MAGGI research group at the Max Planck Institute for Comparative Public Law and International Law in Heidelberg. I specialize in international relations and comparative foreign policy analysis. My research focuses on (1) the impact of polarization and populism on democracies' foreign policymaking; (2) resilience and transformation of Global Governance; and (3) international relations of East Asia and the Asia-Pacific. More generally, I am interested in how the interplay between domestic and international politics affects states' roles in the areas of security, trade, and democracy.

I have published three books: U.S. Global Leadership Role and Domestic Polarization: A Role Theory Approach (Routledge), The Politics of Resilience and Transatlantic Order (co-edited with Sebastian Harnisch & Cameron Thies, Routledge), and National Role Conceptions in a New Millennium: Defining a Place in a Changing World (co-edited with Michael Grossman and Francis Shortgen, Routledge). My research is also published or forthcoming in International Studies Review, Foreign Policy Analysis, International Politics, Journal of Global Security Studies, International Relations, India Review, and The Korean Journal of International Studies.

In addition to research, I teach courses about International Relations Theory, U.S. Foreign Policy, Conflict and Cooperation in the Asia-Pacific, Regional Governance, the European Union, Qualitative Methods, and Global Order. I taught at the Universities of Heidelberg and Freiburg, the German-Turkish University in Istanbul as well as the Graduate Institute in Geneva. I am also a Fulbright Schuman alumni.
