Current Research

My research is situated at the intersection of Digital Journalism, Political Communication, Public Sphere theory, and Digital Methods. I am interested in how the internet contributes and facilitates the formation of communities and the role journalism plays for these groups. More specifically, I am interested in the role social media and algorithms, and generative AI play for the formation of communities and what that means for society.

In the past, my research focused on climate change skepticism in Germany and the far-right in Germany and the United States. This research has been published in high quality peer-reviewed journals and the book “Like, subscribe, radicalize: The internet in the hands of the far-right” on the far-right in Germany and the U.S. is forthcoming with Oxford University Press. My research has been covered by news outlets such as The New York Times (U.S.), The Guardian (U.K.), Süddeutsche Zeitung (Germany), O Globo (Brazil), La Stampa (Italy), or El Mundo (Spain) and was featured on The New York Time’s The Weekly (Episode: The Rabbit Hole). At Suffolk, my research focuses on generative AI and its impact on mis/disinformation. Selected Publications
