I am an Associate Professor and ARC Future Fellow in the School of Philosophy at the Research School of Social Sciences, Australian National University. I am also Director of the Centre for Moral, Social and Political Theory and Co-Editor of The Journal of Political Philosophy. My work is primarily in moral and political philosophy but also engages with related issues in epistemology, philosophy of law and philosophy of social science. I am the author of two monographs, Contractualism and the Foundations of Morality (OUP, 2010) and Explaining Norms (OUP, 2013) and many articles in journals including Ethics, Mind, Noûs, Philosophical Studies and Philosophy & Public Affairs. My current research investigates the nature and proper role of feasibility in politics.
