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:
- I am part of the team organising the XXXVIII International Sunbelt Social Networks Conference that will
take place in Utrecht, the Netherlands, in the week of June 26-July 1, 2018.
- June 7, 2018, I will act as featured speaker at the 11th Annual INAS Conference on Analytical Sociology. My talk's title: 'Is generative sufficiency sufficient? Allocating macro outcomes to competing micro mechanisms'. The conference will be
held at Stanford University,
organised by Eva Meyerson-Milgrom.
- February 8, 2018, I gave a talk titled 'Applying a mechanism-based approach to
the study of economic and societal phenomena' (with Karl Wennberg) to the
workshop 'Towards a mechanism-based approach in sustainability science',
co-organised by Institute for Analytical Sociology and Stockholm Resilience
Centre at Kungliga Vitterhetsakademien.
- November 17, 2017, I contributed to a lecture titled 'Big data analysis of Spotify- and
Flashback data' (with Martin Arvidsson, Niclas Lovsjö, and Marc Keuschnigg) presented at the workshop 'Using Big data in management,
organizational and social systems sciences', organised at Chalmers University
of Technology by Hanns
Hellsmark and Jonas Nässén.
- October 13, 2017, I gave a talk titled 'Stochastic actor-oriented network evolution
models as simulation tools: the cases of echo chambers and peer-led interventions' at
the Workshop on Agent-based Modelling and Simulation of Social
Behaviour the University of
Bremen. My host was Michael Windzio.
- March 28, 2017, I gave a lecture titled 'Social ties and the academic self. A
multilevel network study' at the Swedish Institute for Social Research of Stockholm University. My host was
- Together with Åsa Wallhagen and Niclas Lovsjö,
I was organising the 9th
Winter School on Longitudinal Social Network Analysis & Advanced Siena Users' Meeting
(ADSUM-2017) that took place at the Norrköping campus
of Linköping University in the week of 6-10 February 2017. Teachers of the course
were Tom Snijders,
Johan Koskinen and Per Block (all AdSUM) and myself (winter school).

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!
