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 can make decisions under risk and uncertainty. I'm working on a book, provisionally called Duty Under Doubt: Deontological Decision-Making with Imperfect Information. Together with a group of philosophers, computer scientists, and social scientists, I'm also starting a new project on Humanising Machine Intelligence.
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. The book is the subject of a symposium in Law and Philosophy, available online now.
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, 2018), Australasian Journal of Philosophy (2015), Nous (2017), Philosophical Quarterly (2018), Philosophical Studies (2017), Oxford Studies in Political Philosophy (2017), and other leading moral and political philosophy journals. See 'Research' for more. I'm also an Area Editor at Ergo, an editor of Philosophers' Imprint, and on the editorial board of Oxford Studies in Political Philosophy.
In 2011 I was awarded the Frank Chapman Sharp Prize, the American Philosophical Association's prize for the best unpublished monograph on the philosophy of war and peace, and in 2016 I received an Early Career Researcher Commendation from the Academy of Social Sciences of Australia. I'm a Global Ethics Fellow Alumnus 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. Sometimes the nice people at Samyang send me lenses to play with. You can see those pictures here.
