My primary interests are in syntactic theory and the syntax-phonology interface. In brief, I'm curious about how abstract syntactic structures are generated and externalized.
I'm particularly interested in what might be called "interpretable silence" -- ellipsis, null elements, the residue of movement, etc. -- and what these can reveal about the division of labor between the syntactic and phonological modules. Much of my work focuses on ellipsis in particular, and is concerned with pinpointing when and how ellipsis takes effect during the course of the derivation.
