I work on foundational questions in philosophy of language and mind, especially the nature of our linguistic and mental capacities, and their relation.

I also have interests in metaphysics, epistemology, metaethics, philosophy of law, philosophy of games and sport, and the history of 20th century analytic philosophy (esp. Wittgenstein).

Here at PhilPapers I am the editor of "The Basis of Meaning" and "Aspects of Meaning" and most of their subcategories, as well as "Rule-Following".
