Reader in philosophy at the University of Glasgow, I taught previously at Oxford, Bristol, and Nottingham universities, after taking my BA and DPhil at Oxford, either side of an MA at Chapel Hill.

A great deal of my published work centres on the affective or hedonic character -- or valence -- of the mental. More general concerns underlying these preoccupations include the nature of perception and phenomenal consciousness, and in particular the relationship between phenomenology and representation. I've also worked and written on Wittgenstein's private language argument.
