Biography

I am professor by special appointment of Social Divisions between Groups in the Department of Sociology at the University of Groningen, associate professor in the Sociology Department of Radboud University Nijmegen and since February 2025 also vice dean of education of the Faculty of Social Sciences at Radboud University. Before this I was, for quite some years, the program director of the Research Master Social and Cultural Science of Radboud University.

In my research I focus on social divisions between groups; the interplay of segregation, inequality and polarization. I am also interested in how people form relations with others (e.g., friendships, helping, sporting together) and more precisely in the extent to which people coordinate these ‘selection’ decisions. For this I am also developing and exploring new social networks methods suited to test hypotheses on coordinated tie-formation (see RsienaTwostep).

When teaching students, my aim is to feed their scientific curiosity and to help them ask questions that are both scientific innovative and societally relevant.

I see it as my task as vice dean to help my colleagues in maintaining the high quality of our educational programmes and to foster greater (interdisciplinary) collaboration.

On this site you will find pdfs of my papers, some of my R-tutorials (marginal effects, micro-macro models) and an introduction to conceptual models. Conceptual models may help you in organizing your thought process and may help a lay audience in understanding your research ideas. You can still find older versions of my course Social Networks Analysis for social scientists here but I strongly recommend you to check out SNASS to see if I and Bas Hofstra were already able to update the material.

With that, thanks for reading and enjoy!

More of me:


Lately, I have been thinking about how to start a research project on 'Who joins the debate?' (for lack of a better name). Who, when and why do we decide to start, join, or avoid a contested discussion? For example, within our own university walls, when and why do academics decide to (not) express their professional and personal opinions regarding DEI policies, genAI, the budget cuts, or the genocidal violence going on in Gaza? One hypothesis I would like to test is that people may not join political debates because they perceive the debate to be more polarized than it is in reality. I also would like to understand how and when coordination (e.g. "Let us both speak up together against ... .") may lead to more or less representative debates.



I try to hammer to point home that imho the best questions - that combine scientific innovation with societal relevance - arise out of a combination of theoretical knowledge, methodological skills and hands-on experience with different type of data (collection). And yes I know that this seems to contradict the hypothetico-deductive approach but it doesn't. While many of the students I teach want to 'save the world' I am struggling with the fact to so many of them are quite privileged and have not experienced themselves (or not even seem to know persons who have experienced) discrimination, poverty, etc. Don't get me wrong, I am definitely not saying that lived experience is essential for insight into social phenomena like inequality and segregation but it sure as hell does help in understanding what we are talking about in our - at times - abstract and somewhat detached scientific papers.



While the current budget cuts present many challenges, they also bring new opportunities. There is momentum for change, for example, to foster greater interdisciplinary collaboration within and between faculties and to regain focus on our core tasks: providing high quality education and research. If it is up to me: less bureaucracy (duh); less (graded) exams (and more time for teaching); less unscalable teaching innovation experiments (more adoption of effective innovative teaching methods and more teacher autonomy); less coaching by teachers (more attention for diverse student needs in University Teaching Qualification tracks).

Migratie: Hoe leven we samen?

In 2022 kwamen 400.000 migranten naar Nederland. Dat zijn de kale cijfers. Maar wie zijn die mensen eigenlijk? Waar komen ze vandaan, en blijven ze hier? En wat zijn de gevolgen ervan voor de samenleving? Samen met Helga de Valk, hoogleraar en directeur van het Nederlands Interdisciplinair Demografisch Instituut (NIDI) en psychiater Shoaib Hoshmanden, mocht ik hier iets over vertellen tijdens de publieksacademie sociale wetenschappen in het Forum. Dit krantenbericht verscheen naar aanleiding hiervan in het Dagblad van het Noorden.
