About

I am an associate professor of political science and data science at the University of Copenhagen and the Center for Social Data Science. I am also a faculty research affiliate at the Center for Social Media and Politics at NYU. My current research is funded by an Independent Research Fund Denmark (DFF) Sapere Aude grant to examine how political discourse can be better understood and improved, with particular attention to the role of AI-based tools.
