I specialize in the philosophy of language, philosophy of mind, and epistemology. I have published articles on Quine, Davidson, Dummett, Grice, meaning and interpretation, conceptual relativism, deflationism, self-knowledge, introspection, and ethical expressivism.
More recently, I have been working on the topic of continuities between linguistic and non-linguistic communication and expressive behavior. In 2009, I received a 3-year NSF grant for collaborative research (with Mitchell Green) for the project: Communication, Expression, and the Origins of Meaning.
I recently founded the "Expressive Communication and Origins of Meaning" (ECOM) Research Group. Our website (link on the left) has information about our research, publications, and ways to get involved.
I am currently working on:
- A book manuscript, Expression, Action, and Meaning (tentative title)
- A book manuscript, If Truth Be Told (with Keith Simmons)
- "Origins of Meaning: Must We 'Go Gricean'?" (submitted)
- "Expressive Behavior and 'Continuity Skepticism'" (submitted)
- "Varieties of Expressivism" (for Philosophy Compass)
- "Gorillas, the Birds, and the Bees"
- "Origins: Subjective, Objective, Intersubjective" (with Matthew Priselac)
