I am a Lecturer in Philosophy at Royal Holloway, University of London, and a Visiting Research Fellow at King's College London, where I am affiliated with the Ancient Commentators on Aristotle project. I am also a member of Wolfson College, Oxford, where I was once a Junior Research Fellow.

I have taught Philosophy at a number of other institutions, most recently Birkbeck, University of London. I completed my MA and PhD at the University of Warwick. ​I first studied Philosophy as an undergraduate at St David's University College, a constituent college of the University of Wales, and (founded 1822) the oldest University in England and Wales after Oxbridge (pictured above).

I have wide interests in the history of philosophy, working Hellenistic and Roman philosophy, Renaissance philosophy, and early modern philosophy. In particular I have worked on ancient Stoicism and its later influence. I am especially interested in the different ways in which philosophy as been conceived as a subject, and have written about the ancient idea of philosophy as a way of life.
