Welcome to my personal homepage! I am Professor for Methods of Comparative Political Research at the Cologne Center for Comparative Politics at the University of Cologne. My primary research interests are social science methods with an emphasis on causal inference, qualitative and multimethod research, and research transparency and reproducibility. Substantively, I sometimes work on political parties and party politics.
If you are interested in what DORA is, here is information about the Declaration on Research Assessment.
