I am a quantitative sociologist with a broad interest in criminological topics through a causal inference lens. In particular, I am curious about policing, interpersonal and political violence, historical criminology, and policy evaluation. I try to achieve a better understanding of these issues through open science, causal inference, computational methods, and mechanism-based explanatory frameworks. My work has appeared in outlets such as Journal of Criminal Justice, Journal of Experimental Criminology, European Journal of Criminology, Policing & Society, Policing. A Journal of Policy & Practice and others.

Currently, I am working as a post-doctoral researcher at the Institute of Sociology and Social Psychology at the University of Cologne, where I am contributing to the DFG funded project “Juvenile delinquency in urban school and residential contexts” lead by Clemens Kroneberg. Before that, I held research and teaching positions at the University of Utrecht (The Netherlands) as well as the German Police University in Münster.

You can find information on my current pre-prints and preregistrations on my OSF profile https://osf.io/rpumf/

There, you can also find software code to replicate the analyses from my publications. Most of the code is in R. Some of my older publications still use SPSS or a combination of different software packages.
