Research summary

My research is primarily in epistemology, particularly on scepticism, infallibilism and epistemic antirealism. My PhD project defends an infallibilist and sceptical account of knowledge and argues in favour of an antirealist solution to the sceptical puzzle. This solution, called ‘Epistemic Fictionalism’, allows knowledge claims to be true if uttered in a fictionalist spirit, while nonetheless being literally false outside of the fiction. The aim is to develop a fictionalist theory of knowledge that respects both the intuition that scepticism threatens ordinary knowledge claims, and the intuition that ordinary knowledge claims are for the most part true.

I also have wider research interests in antirealism more generally, in meta-ethics and in philosophical methodology.
