Research interests

Rationality and the relation of rationality and normativity. My work here includes practical reason and also the relation of rational belief and the ethics of belief. 

The application of formal methods to philosophical questions. My work here includes papers on metaphysics, epistemology and paradox.


I did my doctorate at the University of Nottingham, giving a Humean answer to the question of why we ought to be rational. I have lectured at the Universities of Nottingham, Warwick and Aberdeen and immediately prior to taking up my lectureship at Cardiff was a research fellow in the faculty of philosophy at Oxford.

Meysydd goruchwyliaeth

I am interested in supervising research in the following areas:

Rationality and the normativity of rationality.
Formal theories of rationality and epistemology.
Formal methods and problems in metaphysics.
