  • Profile

    I am a postdoctoral researcher within the TWON (Twins of Online Networks) EU Horizon project of Dr. Damian Trilling and member of the EU COST OPINION network. Together we investigate the influence of algorithmic design on democratic debate quality of online platforms. I have a broad and interdisciplinary research interest combining (political) communication science with psychology and computational methods. Before rejoining the Political Communication (PolCom) group at the Amsterdam School of Political Communication (ASCoR), I worked as a methodologist at the Dutch public broadcaster (NPO), worked as an Assistant Professor of Philosophy, Politics and Economics (PPE) at the Vrije Universiteit (VU) Amsterdam, and a postdoc on the NWO VIDI High-Risk Politics project of Prof. Barbara Vis at that same university studying how heuristic biases influence decisions by politicians. My PhD was on the effect of media coverage of opinion polls on political behavior (supervised by Dr. Andreas Schuck and Prof.dr. Claes de Vreese, completed at UvA, 2017).
