I am a Professor of Philosophy at the University of St Andrews.

I am working on a project concerning the ethics and epistemology of trust, promising, and competence.  I say something about that project here.  During 2014-16 I was fortunate to be supported by a Leverhulme Major Research Fellowship, and during 2016-17 by funding from the Philosophy and Science of Self-Control project at Florida State University.

I am a member of the board of the St Andrews Centre for Exoplanet Science.

My other main area of research is metaphysics, where I have written about persistence, identity, time, and other weighty matters.
