David O’Brien is an assistant professor of philosophy at Tulane University, jointly appointed in Tulane’s political economy program. He also currently serves as interim director of the Center for Ethics and Public Affairs at Tulane’s Murphy Institute. David has research interests in normative ethics, political philosophy, metaethics, and the philosophy of education. His recent work focuses on questions in the ethics of distribution—in particular, questions about the nature, scope, and basis of a moral concern for distributive equality. His work has been published or is forthcoming in the Journal of Moral Philosophy, the Journal of Ethics and Social Philosophy, Utilitas, Synthese, and the Journal of the American Philosophical Association. While at Harvard, David will be working on a project that investigates the prospects of explaining the non-instrumental badness of distributive inequality.
