Since October 2020, I am Professor of International Organizations at the Department of Politics and Public Administration at the University of Potsdam.

Previously, I have been working at  Stockholm University, the University of Konstanz (Dr. rer soc., 2009), the University of Hamburg, and the Max Planck Institute in Bonn.

My research is focussed on the design and performance of international organizations, democracy and legitimacy in global governance, and transnational processes of diffusion and learning.

You can find an overview of my research and recent papers on ResearchGate and Academia.edu.
