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 Journal of Politics, Political Communication, Political Science Research and Methods, and the European Journal of Political Research, 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, 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 various interactive graphs and detailed information on the underlying method.
