Yaohui Chai

Dr. Chai earned his Medical Degree at Central South University Xiangya Medical School, China. This was followed by a residency in internal medicine at Gulou Hospital, Nanjing University College of Medicine, China. Then he went on to obtain a M.D./Ph.D. in neurology and neuroscience from the Institute of Neurology, WHO Collaborating Center for Research and Training in Neuroscience, Shanghai Medical University. Dr. Chai worked as a postdoctoral research fellow and then as a research investigator in the Department of Neurology at the University of Iowa Carver College of Medicine. Dr. Chai focused on the polyglutamine expansion diseases, including several inherited ataxia and Huntington’s disease, and had several publications in peer-reviewed journals.

Dr. Chai then completed an internship, a three-year neurology residency, and fellowship training in clinical neurophysiology and neuromuscular medicine at the University of Tennessee Health Science in Memphis. The fellowship training included EMG, neuromuscular diseases, EEG, and Evoked Potentials. He then joined Wesley Neurology Clinic and actively participated in the diagnosis, management, and research of neuromuscular diseases both in Wesley Neurology Clinic and Muscular Dystrophy Association Clinic in Memphis. Some of Dr. Chai’s recent publications include articles in Muscle & Nerve, Neuromuscular Disorders, and Journal of Clinical Neuromuscular Disease. His research interests now include neuromuscular disorders, especially muscular dystrophy, inflammatory myopathy, autoimmune neuropathies, and amyotrophic lateral sclerosis.

In addition to his research experience, Dr. Chai has extensive teaching experiences in neurology, including a current teaching position with the University of Tennessee Health Science Center. He mentors medical students, neurology residents and fellows in clinical neurophysiology.

Dr. Chai is board certified by the American Board of Psychiatry and Neurology and the American Board of Electrodiagnostic Medicine. He is a member of the American Academy of Neurology and the Tennessee Medical Association, and Fellow of the American Association of Neuromuscular & Electrodiagnositic Medicine.
