I am currently Principal Investigator for the Economic and Social Research Council-funded 2016 Welsh Election Study, which is the most ambitious study ever conducted of a devolved election in the UK. Prior to this I was Principal Investigator for the 2011 Welsh Referendum Study and the 2011 Welsh Election Study (both of which were also funded by the Economic and Social Research Council).
Much of my early published work examined political representation in the European Union. I authored Becoming Europeans? Attitudes, Behaviour and Socialisation in the European Parliament (Oxford University Press, 2005) and co-authored (with David M. Farrell) Representing Europe’s Citizens: Electoral Systems and the failure of Parliamentary Representation in Europe (Oxford University Press, 2007).
More recently my main focus has been on elections, public opinion and the politics of devolution. Among my major publications here was Wales Says Yes: Devolution and the 2011 Welsh Referendum (University of Wales Press, 2012), which I co-authored with Richard Wyn Jones. I am also author of the forthcoming The End of British Party Politics? (Biteback), and am currently working on a major study of Elections in Wales: Democratic Politics in a Semi-Sovereign Nation (University of Wales Press).
In addition to these books, I have published more than fifty articles in major academic journals over the years including the British Journal of Political Science, Electoral Studies, the European Journal of Political Research, Legislative Studies Quarterly, Party Politics and Publius, and have contributed chapters to nearly thirty books.
I frequently contribute to discussions of elections, devolution, European politics, the impact of Brexit on the UK, and other political topics. I regularly appear on BBC television, ITV, Sky News, Radio 4, Radio 5 Live and other stations; during the 2017 general election I also appeared on American National Public Radio and on the Australian Broadcasting Corporation's Foreign Correspondent programme. I regularly contributes to the New Statesman and Spectator, and have also authored pieces or been quoted extensively in the Guardian, Sunday Times, Economist, Financial Times and many other publications.
I am Associate Editor of Parliamentary Affairs, a Fellow of the Learned Society of Wales and of the Royal Statistical Society, and an Academician of the Academy of Social Sciences.
