I joined the Faculty in 2015, and am a Fellow of Lady Margaret Hall. I was an undergraduate in Classics at Cambridge University, where I also did my PhD. I was elected to a Research Fellowship at Clare College Cambridge in 1987, and in 1989 joined the Faculty of Philosophy in Cambridge as an Assistant Lecturer, becoming a Senior Lecturer in 2000. I was a teaching Fellow of Clare College from 1990-2007, and an Emeritus Fellow thereafter. In 2007 I moved to the University of Virginia as a Professor of Philosophy. I have held visiting positions at Princeton, Harvard, Merton College Oxford and University College London, and a part-time position at the University of Kent. In 1998-9 I spent a year as a Visiting Fellow at the Center for Hellenic Studies Washington DC, and in 2001-3 I was a British Academy Research Reader. This year I am a Visiting Fellow in Philosophy at Ludwig Maximilian University, Munich, supported by the Alexander von Humboldt Foundation and the Carl Friedrich von Siemens Foundation.
