D.Phil and BPhil., Balliol College, Oxford. B.A., Yale. My current research interests encompass the value and metaphysics of risks and chances of benefits; reciprocity and cooperation; risk-pooling, pensions, and insurance; property ownership and the nature of money; left-libertarianism versus social democracy and socialism; prioritarianism, egalitarianism, and the separateness of persons. I am now completing a book arising from my 2020 Oxford Uehiro Lectures, entitled How to Pool Risks across Generations: The Case for Collective Pensions (Oxford University Press, forthcoming). I have previously taught at UCLA, University College London, and the London School of Economics.
