I am a Professor of Philosophy, and Director of the Global Priorities Institute, at the University of Oxford.
My current research focuses on various issues in moral philosophy. My interests include: foundational issues in consequentialism ('global' and 'two-level' forms of consequentialism), interpersonal aggregation, population ethics (pure and applied), effective altruism and global prioritisation, the interface between ethics and economics, and formal epistemology. At the Institute for Futures Studies I participate in the research project: Climate ethics and future generations.
