Dirk Leuffen

Dirk Leuffen is a Professor of International Politics at the Department of Politics and Public Administration at the University of Konstanz. Since April 2024, he has served as the University of Konstanz' Vice Rector for Research, Innovation and Impact, having previously held this position from 2015 to 2019. He is also a representative of the German Rectors' Conference (HRK) in the Committee for the selection and evaluation of International Max Planck Research Schools (IMPRS) since 2019. Leuffen directs the project 'Conditions of European Solidarity' (CONSOLI) with Sharon Baute at the Cluster of Excellence on the Politics of Inequality, and has led multiple significant research projects including 'EU3D: EU Differentiation, Dominance and Democracy' and 'EMU-SCEUS - The Choice for Europe since Maastricht.'

Leuffen earned his doctoral degree from the University of Mannheim and previously worked as a Senior Researcher at ETH Zurich before joining the University of Konstanz.

Professor Leuffen's research focuses on European integration, with particular emphasis on differentiated integration, decision-making processes within the European Union, and the interplay between domestic and international politics. His work examines how citizens perceive and respond to various forms of European integration, with a strong interest in the legitimacy of differentiated integration arrangements and public support for European solidarity. He investigates political preference formation, particularly how crises like the Eurozone crisis and the COVID-19 pandemic shape European policy preferences. His research combines theoretical frameworks from political science with empirical analysis of public opinion data across multiple EU member states.

His recent publications reveal a strong focus on how democratic backsliding affects European solidarity, the role of fairness considerations in citizen evaluations of EU policies, and the institutional design features that foster public support for differentiated integration. Leuffen's work often employs experimental methods and comparative survey research across multiple European countries, demonstrating a methodological sophistication that bridges qualitative and quantitative approaches. His research consistently addresses the tension between national sovereignty and European integration, examining how citizens balance concerns about national autonomy with support for European cooperation.

As Vice Rector for Research and a principal investigator on multiple major projects, Leuffen has secured significant research funding and leads interdisciplinary teams examining the politics of inequality and European integration. His leadership extends beyond his institution through his role in the German Rectors' Conference, where he influences national research policy and evaluation frameworks.

Leuffen is an active member of the Cluster of Excellence on the Politics of Inequality at the University of Konstanz, where he contributes to the research group 'Political Science & International Politics.' His work often involves collaboration with researchers across Europe, reflecting the transnational nature of his research focus on European integration and solidarity.
