I am a Senior Lecturer in Philosophy, and a Fellow of St John’s College, at the University of Cambridge. I mostly work on logic, mathematics, language, and meta(meta)physics.

Sean Walsh and I published Philosophy and Model Theory in 2018. I published The Limits of Realism in 2013. Most of my current research is on solipsism and the self in the period 1926–69. I have also been thinking about the universal set.
