Current Research Interests:
Speech motor control, with focus on auditory-motor interaction and integration
Using neuroimaging (fucntional MRI) to study the neural mechanisms underlying speech motor control
The mechanisms underlying persistent developmental stuttering
Relations between structural properties of the brain (e.g., white-matter diffusion measures) and speech motor capacities in people who stutter and normal speakers
Primary Research Tools:
Real-time digital speech processing and synthesis
MRI: functional MRI, diffusion tensor imaging
Electromagnetic articulography (EMA)
Psychophysics: perception and perception-motor interactions
Past Research Experience:
Single-neuron electrophysiology of the auditory pathway: with focus on cochlear nucleus and sensorineural hearing loss
Visual prosthesis: with focus on psychophysics and simulation
