About Me

I am a Professor of Political Science at University College London. I have been Head of Department from October 2021.

Recently, my research has focused on developing new designs for highly multidimensional survey experiments that enable us to better measure key concepts relevant to public opinion and political behaviour. This has included projects introducing new methods for measuring the relative importance of different issues to voters; the extent to which there are robust patterns in which kinds of political arguments are persuasive; public preferences over the composition of government spending; public attitudes towards alternative ways that governments raise tax revenues; the extent to which political disagreement can be ascribed to moral disagreement; and the relative perceived severity, and priority for government action, of different politically salient problems. In addition, I am working on a textbook on social science measurement, a book on the structure of public opinion and voter behaviour, and a project examining public attitudes to democracy in the UK.

Earlier in my career, my research was focused on the development of new methods for the measurement of political preferences from large observational survey, voting, network and text datasets. This work included applications to citizens, legislators and judges across the US, UK, EU and beyond.

I worked as a Senior Data Science Advisor to YouGov from 2016-2021 and was an Associate Editor of the American Political Science Review from 2016-2020. Before joining UCL, I worked at the London School of Economics as a Lecturer, Associate Professor, and Professor from 2011 to 2018.

I have just completed a 3.75 year tenure as an associate editor of the American Political Science Review. Over that time, as one of six associate editors, I have managed the review process for 742 manuscripts, about 200 per year. Here are some departing thoughts on the job in no particular order and with no overarching thesis. I wish the new editorial team well. Being an editor is a constant, low-level source of stress.

The slide deck linked below reports an initial performance review for the YouGov MRP model of the 2019 UK general election. As I noted in a series of tweets the day after the election the overall performance was mixed. The headline Conservative seat prediction was too low (339 vs 365), but on many other metrics the model performed well, capturing many important features of how party vote shares changed across UK constituencies versus the previous election in 2017.
