I’m Assistant Professor of International Security at the Department of Political Science and Public Administration at Vrije Universiteit Amsterdam. Previously, I was Visiting Scholar and Interim Franz Haniel Professor at the Willy Brandt School of Public Policy at the University of Erfurt and Research Associate at the Chair of European and Global Governance at the Munich School of Politics and Public Policy. I hold a PhD in Political Science from Humboldt-Universität zu Berlin and a Habilitation (venia legendi) in Political Science from the Technical University of Munich. As a Post-Doctoral Researcher I have worked at the Technical University of Dresden and the Technical University of Munich.

My research focuses on international and comparative politics, foreign and security policy, and comparative methods. My book Democratic Participation in Armed Conflict: Military Involvement in Kosovo, Afghanistan, and Iraq (Palgrave Macmillan, 2014) examines pathways toward war involvement and war abstention across 30 democracies and their participation in contemporary conflicts. The book received the Dissertation Award from the German Political Science Association (DVPW).

My book Qualitative Comparative Analysis: An Introduction to Research Design and Application (Georgetown University Press, 2021) offers a comprehensive and up-to-date introduction to QCA, with step-by-step guidance on how to turn a research project into a QCA study and how to interpret and present analytical findings. The book is illustrated with empirical examples from across the social sciences.
