I am a Professor of Philosophy & Logic, and Head of the Philosophy Department, at UCL.

I work at the area where philosophy meets mathematics and logic. Right now, I am thinking about theoretical equivalence, types, and sets.

I recently published a serialized trilogy on Level Theory at BSL. Before that, Sean Walsh and I published Philosophy and Model Theory (OUP, 2018). My first book was The Limits of Realism (OUP, 2013). I have made some open education resources. I am an associate editor of MIND.
