My interests lie in moral and political philosophy and practical rationality, as well as intersecting areas in law, economics, and political science. My published research focuses in particular on questions about distributive justice, including ones arising across states and generations. I explore how egalitarian distributive principles should guide the design of social institutions that shape the prospects of children, parents, the elderly, and future generations. I have a longstanding interest in the role that demographic factors should play in our response to climate change. My most recent work examines how policy makers should deal with inequalities in lifespan and why they should care about gender gaps in labour markets; see, for example, 'What Makes the Gender Pay Gap Unjust?', forthcoming in Oxford Studies in Political Philosophy, Volume 12 (2026) and co-authored with Tom Parr.
