Communication is one of the most important abilities that humans possess. The loss of this ability can be devastating. Our research is aimed at furthering our knowledge of how the brain allows us to communicate; in particular, how it enables us to produce and understand speech. In addition, we study neurogenic communication disorders (speech and language problems caused by brain damage, such as stroke), with the aim of improving treatment for these disorders. We employ a variety of research techniques, including the perceptual and acoustic analysis of speech, functional magnetic resonance imaging (fMRI), and transcranial magnetic stimulation (TMS). Our research on speech recovery after stroke is currently funded by the National Institutes of Health.
