I am a research associate and junior lecturer at the Department of Communication Science, Faculty of Social Sciences, at Vrije Universiteit Amsterdam (2023–today). My research focuses on public opinion, polarization, the spread of misinformation, conspiracy theories and conspiracy beliefs, and trust in media. I teach courses in communication science (BSc and MSc), as well as in the Research Master Program Social Sciences for a Digital Society. You can visit my profile at Vrije Universiteit Amsterdam here.
