I am currently Director of the Research School of the Social Sciences (RSSS) at the Australian National University, where I’ve also been a member of the School of Philosophy since 2007. I work mostly in moral and political philosophy, with a focus on issues of international justice. Lately I’ve been working with on the topic of the ethics of imposing risk on others and on broader questions of environmental philosophy, particularly in relation to net zero targets. My publications include books with Sanjay Reddy, International Trade and Labour Standards: A Proposal for Linkage (Columbia University Press, 2008), and Gerhard Øverland, Responding to Global Poverty: Harm, Responsibility, and Agency (Cambridge University Press, 2016), and articles in many journals in philosophy, politics, and law. I used to edit the journal Ethics & International Affairs and am currently Co-Editor Political Philosophy and Associate Editor at Ethics. I’ve done two stints as Head of School in Philosophy at the ANU (2016-18, 20-21) and was a Deputy Director of the Research School of the Social Sciences (2012-2014). I was elected Fellow of the Academy of the Humanities of Australia in 2019. I’m currently working on two books, one (with Kate Macdonald) on ethical consumerism, the other (with Garrett Cullity) on the ethics of net zero, both of which are under contract with Oxford University Press.
