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 and decision theory, although I am also interested in formal epistemology, the philosophy of mathematics, the philosophy of physics, and many other areas.
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.
