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 and qualitative and multimethod research. Substantively, I sometimes work on political parties and party politics.
