My research focuses on the L1 acquisition of the syntax and semantics of the Determiner Phrase. I am interested in the relationship between L1 acquisition, grammaticalization and diachronic change.

I am fascinated by all aspects of syntax, psycholinguistics and the syntax/semantics interface. These days a growing percentage of my research is devoted investigating Augmentative and Alternative Communication (AAC). I am curious about how linguistics can inform the field of AAC. I am also keenly interested in how users of AAC, who generally have some period of being immersed in language without being able to produce it, may inform us about language acquisition and the nature of human language.

My students are highly encouraged to assist me in my research and I attempt to bring empirical work into the classroom as often as possible.
