About Me

I am an Assistant Professor and Ad Astra Fellow in the School of Politics and International Relations at University College Dublin. Previously, I was a Senior Researcher at the University of Zurich.

My research focuses on political representation, party competition, political communication, public opinion, quantitative text analysis, and the application of computer vision techniques. My work has been published in journals such as the American Political Science Review, The Journal of Politics, Political Communication, the European Journal of Political Research, and Political Science Research and Methods, among others.

I am a founding member of the Connected_Politics Lab, a non-resident fellow at the Digital Democracy Lab at the University of Zurich, a member of the UCD Energy Institute, co-author of the quanteda R package, and maintainer of the Irish Polling Indicator.

Irish Polling Indicator

The Irish Polling Indicator is a joint project with Tom Louwerse. We combine all opinion polls for the Dáil Éireann into daily estimates of public support for Irish parties. The website of the Polling Indicator provides interactive graphs and detailed information on the underlying method. UCD Expertise recently featured the Polling Indicator and related research.

The figure below (updated automatically after the release of new polls) reports the most recent estimates of party support.
