Speech Production and Speech Motor Control

Current Research Interests

Research focuses on the neural and sensorimotor mechanisms of spoken language production, perception and their interaction using a variety of techniques including functional and structural neuroimaging, transcranial magnetic stimulation, electroencephalography, auditory and somatosensory perturbation, electromyography and kinematics. We are also studying neurobehavioral changes associated with speech motor learning and speech motor disorders.
