What I do
I work as a mathematical sociologist and network researcher at the Interuniversity Centre for Social Science Theory and Methodology
(ICS, Department of Sociology, University of Groningen) and at the
Institute for Analytical Sociology (IAS, Department of Management and Engineering, Linköping University).
My research focuses on the formal modelling and inferential-statistical analysis of socio-centric social networks, and - since short - on the network analysis of register data.
My published work is focused on the formal modelling of social network structure and social network dynamics, with emphasis on social influence processes in the context of a changing network. Over the years, my work has shifted to a broader orientation, including networks in educational settings, the co-evolution of multiple networks, and the analysis of emergent macro- and meso-level phenomena by micro-level modelling, such as normative behaviour, social hierarchies, and subgroup structures in networks.
In my work, I combine empirical calibration of models to data sets for purposes of statistical inference with empirically informed simulation studies. Far too often in empirical network research, hypotheses are formulated with insufficient consideration of what the null hypothesis should be. In social simulation studies, a related predicament is the study of simulated networks that do not match their empirical counterparts on important dimensions.
Some temporally close events and activities that I will be (or recently have been) involved in are these:
- November 16-17, 2019, I will hold the keynote lecture titled 'Social network mechanisms' at the 31st Annual Dokkyo International Forum at Dokkyo University in Saitama, Japan. My host will be Hideki Fujiyama.
- June 13-14, 2019, I contributed a talk titled 'Analysing labour mobility networks from administrative register data' to the workshop How to Analyze Large-Scale Network Structures?, organised by Philipp Brandt, Sebastian Pink, and Katharina Burgdorf in Mannheim.
- June 11, 2019, I contributed a talk titled 'An empirically calibrated, counterfactual study of echo chambers' to the workshop Complex Systems perspectives on Algorithmic Bias, organised by Joseph Kenny and Ancsa Hannak as part of the International Conference of Web and Social Media (ICWSM-2019) in Munich.
- Together with Robert Krause, Christine Timmerman, and Tom Snijders, I was running the 10th
Winter School on Longitudinal Social Network Analysis & Advanced Siena Users' Meeting
(ADSUM-2019) that took place at the University of Groningen in the week of 14-18 January 2019.

How I came here
My first academic education was a study of mathematics and information science at
the TU Berlin.
Not wanting to spend my life proving theorems or optimising some company's profits, I got enticed with the idea of applying mathematical thinking and modelling in the still thoroughly underformalised social sciences. The opportunity to do so came when the ICS Research School accepted me as a Ph.D. candidate. My thesis project was about the stochastic modelling of cultural and situational context effects on individual decision making. The resulting dissertation entitled The Framing of Decision Situations was defended 18th of September, 2003. Since 2002 I have been working on social networks, beginning with an NWO-funded Dutch national project ('aandachtsgebied') on co-evolving social networks and behaviour. I am grateful for Tom Snijders' mentorship throughout these years!
