Until September 2023 I worked at the Department of Communication Science at Vrije Universiteit Amsterdam working on the OPTED project and AmCAT (Amsterdam Conent Analyis Toolkit. Since April, I also started to work on the NEWSFLOWS project at the Department of Communication Science at the University of Amsterdam. Previously, I worked as Post-Doc Researcher at the Chair for Digital Democracy at the European New School of Digital Studies (ENS), European University Viadrina Foundation Frankfurt (Oder). In 2021, I passed my PhD in Politics at the University of Glasgow.
