I have been an ICREA Research Professor at the Universitat Pompeu Fabra since 2010, where I am a member of the Law & Philosophy research group and of the Barcelona Institute of Analytic Philosophy. I have been an elected member of the Academia Europaea since 2019. Prior to joining ICREA I was Senior Lecturer at the Faculty of Philosophy, University of Cambridge, and Fellow of St. John's College (2001-2010). I had first arrived at Cambridge in 1999, as a Research Fellow at Emmanuel College, after studying at the University of Oxford between 1990 and 1999. At Oxford I obtained a B.A., an M.Phil. and a DPhil.degree.
