Research Interests

My research deals with the relationship between human movement, language and communication, in both clinical and non-clinical populations. Broadly speaking, I am attempting to better understand the structure of sign language, particularly as it relates to the phonetic and phonological units from spoken language, and also to inform the development of sign- and speech-based therapies for neurogenic language deficits. Recently, I have been collaborating with colleagues at Haskins Laboratories to carry out instrumented measures of the coordination of limb gestures and speech prosody in typical speakers.
