MA, DPhil (Oxford)

Academic background

I studied Classics at Corpus Christi College, Oxford as an undergraduate and then wrote a doctoral thesis in Philosophy, on necessity, chance and explanation in Aristotle.  I held college lecturerships at Pembroke, Jesus and Wadham, and have also taught at King's College London, the Open University, and Stanford University.  I held a Junior Research Fellowship at Christ Church 1984–7, and was appointed to an Official Studentship here in 1987.

Undergraduate teaching

I teach most of the Greek philosophy courses on the Oxford syllabus, as well as Ethics and Early Modern Philosophy.

Research interests

My research focuses on ancient philosophy, and especially on the thought of Plato and Aristotle.
