Research
I study social cohesion and migration, with a focus on intergroup relations and political communication, using quantitative and computational methods. My work has received wide recognition, with 1874 citations on Google Scholar (see plot on the right) and being in the top 2% compared to peers with similar academic age on ResearchGate. The findings are featured in national and international media and influenced global and EU-level policy institutions.
I am PI of the project Crossing Boundaries: Migrants’ Attitudes Toward Immigration and Their Political Consequences funded by the Dutch Research Council. I am also a member of SOCION, where I serve as a daily supervisor for PhD project on social cohesion in ethnically diverse schools.
All my studies are freely available, either as open-access publications or as preprints. Interested readers can find the PDFs of the published versions in the list below.
Adhering to the idea of transparent and replicable research, I always upload the code of my published studies to the Open Science Framework. Feel free to use any material for secondary analyses, teaching, or other purposes. If you can’t access something, let me know.
