I am a Professor of Political Science at University College London. From 2011-2018 I was on the faculty at the London School of Economics. I am also currently an Associate Editor of the American Political Science Review (2016-2020) and a Senior Data Science Advisor to YouGov.

Applications of these methods have included citizens, legislators and judges in the US, UK and EU.
