I am a Professor and Head of Department of Political Science at University College London. My research is focused on the development of new methods for the measurement of political preferences and beliefs from survey, voting, network and text data. Currently my work is focused on public opinion and political behaviour in the UK, but my previous research has considered applications to citizens, legislators and judges across the US, UK, EU and beyond.

I have been a Senior Data Science Advisor to YouGov since 2016 and was previously an Associate Editor of the American Political Science Review (2016-2020). I worked at the London School of Economics from 2011 to 2018.
