Areas of Interest

Hasini Weerathunge is a Speech Scientist who uses various techniques ranging from auditory/somatosensory motor perturbations to neurocomputational models to understand and characterize motor speech disorders. Her research interests include understanding the neuropathophysiological of motor speech disorders and developing neuro-engineering applications that enhance the quality of life for those with sensorimotor deficits. As a postdoctoral researcher in the Speech Neurophysiology lab, she is interested in investigating the application of non-invasive neurostimulation techniques to improve the effectiveness of current behavioral approaches to stuttering treatment.
