My research focuses on several challenges that came about with the advancement of digital technologies, such as misinformation, micro-targeting, online content moderation, and - more broadly speaking - the role of social media in our daily media-diet. I am particularly interested in the extent to which the numerous interventions against these potentially harmful phenomena are effective, but especially to what extent such interventions may cause unintended spill-over effects. 


To give an example, in my PhD-thesis entitled "The Remedy Worse than the Sickness? Comparing the Harms of Misinformation to the Media's Interventions Against it", I argue that the amount of attention to misinformation in the media (i.e. the media covering misinformation as an issue) may not be in proportion to the magnitude of the problem of misinformation. Through four independent papers, my thesis shows that such coverage of misinformation may do more harm than misinformation itself by fostering misperceptions and skepticism, and by decreasing trust. 


Method-wise, I enjoy designing survey- and field-experiments, as well as using computational social science approaches such as topic-modelling, webscraping and digital trace-data.
