Dr. Mehdi Bakhtiar is an Assistant Professor in the Human Communication, Development and Information Sciences Unit at The University of Hong Kong Faculty of Education. He received an MSc degree in Speech Therapy from Tehran University of Medical Sciences and worked as a clinician for a few years before pursuing his PhD in Cognitive Neuroscience of Language at The University of Hong Kong. His main research interests are related to the underlying nature of speech disorders in people with stuttering and other neurogenic communication disorders. Mehdi studies the neurocognitive, linguistic and sensory-motor aspects of stuttering and other motor speech disorders. He is also interested in the application of non-invasive brain stimulation methods (e.g., tDCS, TMS) as an add-on treatment for people with neurogenic communication disorders.
