My lab conducts research on the neural bases of developmental stuttering, a neurodevelopmental disorder characterized by frequent occurrences of sound-syllable repetitions, prolongations, and blocks that interrupt the flow and rhythm of speech production. Stuttering affects approximately 1% of the population, and 5% of preschool age children. The cause of stuttering is unknown and treatment options for stuttering are limited. Our studies involve analyses of brain functional and structural measures acquired through multimodal neuroimaging methods such as fMRI, DTI, structural MRI, fNIRS, and EEG. Using these techniques, we are able to examine subtle differences in brain functional and structural connectivity that differentiate people who stutter compared to people who do not stutter. These findings are expected to help lead to further investigations to develop novel treatments for stuttering in the future.
