I am an Assistant Professor of Political Science at the University of Copenhagen and Center for Social Data Science. I am a faculty research affiliate and former post-doctoral researcher at the Center for Social Media and Politics at New York University, and I have a PhD from the University of Toronto. I conduct research on political behavior, social media, and quantitative methods.

I was a partner at, and currently am an advisor for Vox Pop Labs, a company that works with media organizations (e.g. Wall Street Journal, Sky News UK, CBC, ABC) to provide applications that promote political literacy. We are best known for Vote Compass, an application used by millions of voters in recent elections.
