My work is primarily on theories of practical reasons and in action theory. I’ve also looked at some topics in normative ethics. Practical reasons are the leitmotif that connects the different topics I’m working on (e.g. buck-passing accounts of value, the paradox of deontology, promissory obligation). The focus of my current research is on action theory and moral psychology (intentions, responsibility, moral luck).

In 2013-14, I received a mid-career fellowship from the British Academy. I have been working on intentions: what they are; how they relate to the reasons for which we act, whether they are morally significant, and, if so, whether the doctrine of double effect captures how they affect moral evaluation.

In 2014-15 I was a Guest Research Professor at the University of Vienna as part of the ERC funded project Distortions of Normativity. I have been pulling together some of the research I did before, working on a book-length exploration of the relation of intentions, and the reasons for which we act. You can find a list of my publications here.


I normally teach a level 3 module (open to PG students) on Responsibility, Luck and Excuses and Thesis Prep for 1st year MPhil Students in term 1. In term 2, I teach a level 2 module on Matters of Life and Death, as well as a research seminar currently on Practical Reasons and Rationality (the content changes quite a bit from year to year). In the spring of 2020 I will co-teach the research seminar with Joseph Raz.


I'm an Associate Professor and the Graduate Tutor in the Philosophy Department at University College London (UCL).

Before coming to London, I was an Associate Professor in Philosophy at the University of Leeds and before that an assistant professor at the University of Pennsylvania, Philadelphia. I've also held fixed-term positions at Columbia University, and Barnard College, New York, and at Balliol College, Oxford, and I have been a faculty fellow of the Center for Ethics and Public Affairs at the Murphy Institute at Tulane University, New Orleans (2004-5), and of the Safra Center for Ethics at Harvard University (2008-9).  I am a member of the Einstein Ethics Network.  And I did my graduate work at the Free University in Berlin under the supervision of Jay Wallace.
