I have been a Lecturer in Philosophy here since 2018.

My main research interests are in moral philosophy. In particular, I am interested in collective obligations, well-being, value, moral psychology, and effective altruism.

One of my main areas of research so far has dealt with whether groups of people might possess their own normative reasons for action, and how these might be related to the reasons possessed by the individual members of the group. For example, if we ought to do something, does that mean that I ought to do my part?

I have also been interested in issues at the intersection between normative ethics and moral psychology. For example, I have been interested in the 'paradox of hedonism' (the idea that desiring pleasure exclusively can make us less happy), and in whether it poses a problem for the idea that pleasure is what is ultimately desirable.
