I am a senior research fellow in philosophy at the University of Oxford, based at the Global Priorities Institute. My current work is mainly in normative ethics, decision theory, and formal epistemology, although I have also done some work in the philosophy of mathematics and the philosophy of physics.
I was previously a mathematician, working on some topics in representation theory and algebraic geometry. My PhD was from the University of Chicago, and I held research fellowships at Oxford and Edinburgh. Having collaborated on some interdisciplinary projects, I decided to retrain in philosophy, completing a second doctorate at Oxford in 2016.
