Biography

Dr. Na-hyeon (Hannah) Ko is an assistant professor in the Department of Physical Therapy at California State University, Fresno. She received her Ph.D. degree in Biokinesiology at the University of Southern California and M.A. degree in Motor Learning and Control at Columbia University. She obtained her B.S. in physical therapy at Sehan University, South Korea and post-professional Doctor of Physical Therapy at A. T. Still University. Her clinical experience focuses on pediatrics, specializing in early intervention (0-3 years) and children with neurological and genetic disorders. She has practiced in various clinical settings in New York and California. As a professor at Fresno State, Dr. Ko teaches physical therapy management of pediatrics.

Dr. Ko’s research interests are neuroplasticity and neurorehabilitation for individuals with neurological disorders (e.g., cerebral palsy, Parkinson’s disease, stroke, etc.). She is interested in investigating underlying neurophysiological mechanisms of motor control and motor learning when performing complex motor tasks, using non-invasive brain stimulation such as transcranial magnetic stimulation. Furthermore, she would like to develop neurorehabilitation strategies for individuals with neurological disorders to improve motor function by facilitating neuroplasticity in the brain by challenging motor tasks and non-invasive brain stimulation.

Dr. Ko enjoys hiking in the National Parks and exploring the city of Fresno. She has a barista certificate and brews pour-over coffee every morning. She also likes to discuss and share ideas at happy hours.
