I am currently the Stein Rokkan Chair in Comparative Politics at the European University Institute, in Florence.   In January 2027 I will move back to London, to start a position as Professor of Political Science in the LSE School of Public Policy.

I am a Fellow of the British Academy, and a Fellow of the Royal Society of Arts. I am also President of the European Political Science Society.

My main areas of research and teaching are comparative, European, and historical political behaviour and institutions – in particular parties, electoral behaviour, legislative politics, electoral systems, and the design of democracy.
