Research Interests
I am interested in the abilities that allow people to speak fluently and easily. My research focuses on the processes of phonological encoding and articulation described by cognitive theories of spoken word production. I study these processes by investigating the speech and language impairments that can result from dementia, stroke, or traumatic brain injury. I also supervise research projects with unimpaired speakers, investigating speech production in difficult contexts (such as saying tongue twisters or learning the sounds of a foreign language).
