Hi! My name is Marijn

I’m an Analytical Sociologist and–September onward–an Assistant Professor at the Institute for Advanced Study in Toulouse (IAST) & the Department of Social and Behavioral Sciences (SBS) at the Toulouse School of Economics (TSE) in France.

I work on questions around social influence, opinion polarization and identity. Currently, I am working on a project around environmental beliefs and behaviors, and how they are subject to (mis)perceived local norms and identity-biases

My research interests lie, more generally, in understanding unintended macro-consequences of rational micro-behavior. I use methods from analytical sociology and computational social science like formal modeling, experiments and analysis of digital trace data. In my PhD research I focused on the impact of communicating via online social media platforms on processes of opinion formation and the diffusion of culture.

I got my PhD in Sociology from the University of Groningen where I was a member of the Norms and Networks Cluster and the ICS. Before joining the SBS-TSE, I was a Postdoctoral researcher at the Chair of Sociology and Computational Social Science in the Karslruhe Institute of Technology and a Research Fellow at the Institute for Advanced Study in Toulouse.

Here, you can find more about my current projects, general research interests, and publications.

Feel free to get in touch!

Computational Social Science of Social Cohesion and Polarization

What holds societies together—and what drives them apart? As worry over political polarization and social cohesion intensifies across the globe, this volume explores timely and vital questions of social cohesion and polarization through the lens of Computational Social Science. It brings together leading and junior scholars who harness the power of computational methods to analyze, model, and understand discourse, social relationships, and beliefs. Drawing on tools such as agent-based modeling, social network analysis, and natural language processing, the book offers a range of innovative approaches to study how belief systems form, attitudes polarize, and communities fragment.

Aimed at researchers, students, and practitioners across disciplines, this volume is both an introduction to the field and a showcase of its most promising applications. It is an introduction into CSS of social cohesion and polarization, and an invitation to rethink how we study—and perhaps even how we can repair—the social fabric.

This book is part of the Springer Computational Social Sciences series
