Denis Cohen I am a postdoctoral fellow in the Data and Methods Unit at the Mannheim Centre for European Social Research (MZES), University of Mannheim. I am also a co-organizer of the MZES Social Science Data Lab as well as an editor and author of the blog Methods Bites.

My research focus lies at the intersection of political preference formation, electoral behavior and political competition. My methodological interests include quantitative approaches to the analysis of clustered data, measurement models, data visualization, strategies for causal identification and Bayesian statistics.

I hold a BA in Social Sciences from Humboldt-University Berlin (2013) and an MSc in Political Economy from the University of Essex (2014). Prior to joining the MZES, I finished my PhD at the Berlin Graduate School of Social Sciences at Humboldt University of Berlin, where I also worked as a research associate in the Comparative Politics Unit.
