As a fellowship-trained neurologist subspecializing in movement disorders, Dr. Zhang’s primary clinical and research interests are in Parkinson's disease (PD), tremor, ataxia, and other movement disorders. His particular expertise has led him to focus on the epidemiology of PD, exploring whether nutritional deficiencies in certain populations have an impact on PD. He currently serves as Chair of the Working Group on Genetic & Environmental Risk Factors for PD as part of the largest clinical research consortium in the country, the Parkinson Study Group (PSG). As a member site for PSG, the clinical trial program he leads at UC Davis has participated in many multicenter trials testing new medications for PD, several of which are now used in clinical practice. Dr. Zhang’s other clinical and research interests focus on dystonia and related movement disorders such as facial spasm, limb spasticity, and dystonic tremor, all of which can be treated with neurotoxin injections, most commonly botox. He has participated in registry studies and double-blinded clinical trials for neurotoxin therapeutics, and his services presently offer four different types of neurotoxins to accommodate the patient's needs, symptoms, previous exposure to other toxins, and a variety of other indications. Dr. Zhang also serves as the medical director of the Deep Brain Stimulation (DBS) program at UC Davis and he is very interested in the clinical applications of DBS. Under his direction the DBS program of UCDavis has become a referral center that offers implantation surgery weekly and clinical programming visits daily, serving the greater Sacramento area and northern California.
