I work on foundational questions in philosophy of language and mind, especially on our linguistic and normative practices and related mental capacities. I'm currently writing a book about the nature of linguistic meaning.

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".
