Welcome to my homepage. I am assistant professor at the Department of Sociology and the ICS at the University of Groningen.

My general research interest concerns collective action and social integration in social networks. I use computational modeling techniques to develop new hypotheses. To test these hypotheses, I have gathered longitudinal network data in several organizations and conducted laboratory experiments.

I founded the Sociology Laboratory of the Department of Sociology in Groningen, which is a laboratory for behavioural experiments.

I taught model building, sociological theory, and research methodology in the undergraduate Sociology program of the University of Leipzig, the University of Groningen, and at ETH Zurich.

I am a member of the faculty council of the Faculty of Behavioural and Social Sciences at the University of Groningen.
