I have been an ICREA Research Professor at UPF since 2010. Prior to that, I was Senior Lecturer at the Faculty of Philosophy, University of Cambridge, and Fellow of St. John's College, which I joined in 2001. I had first arrived at Cambridge in 1999, as a Research Fellow at Emmanuel College, after studying at the University of Oxford, where I obtained a B.A., an M.Phil. and a DPhil.degree.
