I'm an Associate Professor, and Head of the School of Philosophy, in the Research School of Social Sciences at the Australian National University. I write on topics in political philosophy, and normative and applied ethics. My current research project focuses on how deontologists (roughly, people who think that morality is fundamentally about rights and duties, rather than realising the best consequences) can make decisions under risk and uncertainty. I'm working on a book, provisionally called 'Duty Under Doubt: Deontological Decision-Making with Imperfect Information'.
In my last book, Sparing Civilians (Oxford, 2015), I tried to preserve the protection of civilians in war against political and philosophical threats that have arisen in recent years.
Most of my work has been on the ethics of war, self-defence, and risk, but I have also written on corrective justice, the nature of rights, and associative duties. I've published papers in Ethics (2009, 2015, 2017), Philosophy & Public Affairs (2010, 2012), Australasian Journal of Philosophy (2015), and other leading moral and political philosophy journals. See 'Research' for more.
In 2011 I was awarded the Frank Chapman Sharp Prize, the American Philosophical Association's prize for the best unpublished monograph on the philosophy of war and peace, and in 2016 I was one of three recipients of the Academy of Social Sciences of Australia's Early career commendations. I'm a Global Ethics Fellow of the Carnegie Council for Ethics in International Affairs, and have written op-eds for Boston Review, and recorded interviews with philosophy podcasts such as Public Ethics Radio, Examining Ethics, and Philosophy Bites. In 2013, I was awarded a $366,000 DECRA grant, by the ARC. In 2016, I was lead CI on a Discovery Grant of $335,000, on Ethics and Risk.
I'm also a photographer. All the pictures on this site are my own (except the portrait—that's by Caspar Hare). You can see more of my photos here.
