I am a University Professor of Empirical Democracy Research at the University of Mannheim. Previously, I held positions at the Graduate School of Economics and Social Sciences (GESS) in Mannheim, Goethe University Frankfurt, the University of Essex, the Mannheim Centre for European Social Research (MZES) as well as the universities of Berne and Konstanz. I study the socio-structural and psycho-cultural requisites of democracy with a strong focus on problems of cohesion and conflict. My current research involves the politics of free speech and censorship, citizens’ preferences for migration policy, and the consequences of wartime sexual violence. I also have a keen interest in quantitative political methodology, including Bayesian methods, data visualization and survey experiments. My work has been published in British Journal of Political Science, Comparative Political Studies, Journal of Conflict Resolution, Political Analysis, and Sociological Methods & Research, among others.
