About

I am an associate professor of political and data science at the University of Copenhagen and its Center for Social Data Science. I am also a faculty research affiliate at NYU's Center for Social Media and Politics. I currently hold a Sapere Aude grant from the DFF (Denmark's NSF) to investigate and improve political discourse, with special attention to AI-based tools.
