Currently working on:

- Communication without Common Ground: Arguing for and developing an alternative to the common-ground based model of conversation -- see my recent paper in Linguistics and Philosophy "Availability Without Common Ground"
I've also worked on:
- Implicature: in particular, how to extend the conservative Gricean picture to embedded implicature -- here's a SALT paper on this topic
- Disjunction: this was the topic of my dissertation, which I continued in some early papers -- see this paper for the pragmatics side, and this one for semantics
- Convention: see this joint paper with Kevin Zollman
- Bridging and definiteness: see this recent paper with Hannah Rohde
Other roles:
