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:- 4-8 September 2023, I will participate, with many colleagues, in the 7th European Conference on Social Networks (EUSN 2023) in Ljubljana, Slovenia.
- Together with Tom Snijders and Christine Timmerman, I was organising the 13th Winter School on Longitudinal Social Network Analysis & Advanced Siena Users' Meeting (ADSUM-2023) that took place at the University of Groningen in the week of 30 January to 3 February 2023.
- 31 October-1 November 2022, I taught an invited workshop 'Analysing network dynamics and peer influence processes with RSiena' at the Autumn Methods Workshops at Lund University's Faculty of Social Sciences. My host was Nils Gustafsson.
- I participated in the POPNET Academic Workshop on Population-scale Network Science that took place 24-25 October 2022 at the Institute for Advanced Study in Amsterdam.
- 19 May 2022, I contributed the talk 'Empirically calibrated network simulation as a tool to study social interventions' to The Dutch Network Science Society Symposium that took place in Leiden.
- April 8, 13 and 18, 2022, I was teaching the workshop 'Stochastic Network Modeling: Analyzing the Co-Evolution of Behaviour and Social Networks with SIENA' at the National Institute of Education, Singapore.
- On 28 March 2022, I gave the presentation 'Understanding Social Network Processes: Peer Selection and Influence in Changing Social Networks' at the National Institute of Education, Singapore. My host was Imelda Caleon Santos.
- February 8th, 2022, I gave a talk titled 'Empirically calibrated network simulation as a methodology of the middle range' at the University of Manchester's Social Statistics Seminar Series. My host was András Vörös.
- Together with Anastasiia Menshikova and Madelene Töpfer from Linköping University, I was organising the 12th Winter School on Longitudinal Social Network Analysis & Master Class that took place online 8-11 February 2022.

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!
