Safwan Jaradeh, MD
Professor, Neurology & Neurological Sciences
Director, Autonomic Disorders Program

Dr. Jaradeh's clinical interests include autonomic disorders, small fiber neuropathies and the development of effective methods of testing and treating these disorders. Prior work has focused on small fiber, painful and autonomic neuropathies; syncope and syndromes of orthostatic intolerance including postural orthostatic tachycardia (POTS); gastrointestinal motility dysfunction; cyclic vomiting; neurology of gastroesophageal reflux; non-allergic rhinitis syndromes; and the relationship between the autonomic nervous system and normal or abnormal sleep. Additional areas of interest include the neurology of phonation and swallowing disorders, autoimmune neuromuscular disorders, hereditary neuropathies, and peripheral nerve injury and repair.

Dr. Jaradeh is board certified in Neurology and in Clinical Neurophysiology by the American Board of Psychiatry and Neurology.

Linda Nguyen, MD
Clinical Assistant Professor, Medicine - Gastroenterology & Hepatology

My career has been committed to better understanding gastrointestinal dysmotilities, which encompass a variety of disorders that affect the enteric and/or autonomic nervous system that results in a variety of symptoms. These disorders are often difficult to diagnose and lead to significant morbidity and impairment in quality of life. I am the Director of Motility and Neurogastroenterology at Stanford. I perform approximately 1000 motility studies per year to provide a better understanding of how dysmotilities impact patient symptoms. I have evaluated the influence of manometry and electrogastrography on symptom predominance and treatment outcomes for various therapies including gastric electrical stimulation and intrapyloric botulinum toxin injection. I have been a member of the NIH-funded multicenter Gastroparesis Clinical Research Consortium since 2007. The goal of the Consortium is to perform clinical, epidemiological and therapeutic research in gastroparesis, as well as provide an infrastructure to more efficiently and effectively perform such trials.


Dong-In Sinn, MD
Clinical Assistant Professor, Neurology & Neurological Sciences

Dr. Sinn is a board-certified neurologist in the division of autonomic disorders. After graduating from Seoul National University School of Medicine in South Korea, he completed internship and neurology residency at Seoul National University Hospital. Upon finishing three years of mandatory military service, he came to the United States for a family reason. He did a second neurology residency at Medical University of South Carolina and completed an autonomic disorders fellowship under Drs. Roy Freeman and Christopher Gibbons at the Beth Israel Deaconess Medical Center of Harvard Medical School in 2016. His clinical interests include neurogenic orthostatic hypotension, autonomic neuropathy, postural tachycardia syndrome, syncope and baroreflex failure. He also treats a variety of other autonomic disorders.

Russell Mendonca, BA
Patient Testing Tech Specialist

Russell received his bachelors in Biology and Psychology from the University of California, Santa Cruz. He currently splits his time in the Movement Disorders Balance Lab and in the Autonomic lab. Prior experience includes sports medicine and physical therapy. His interests include neurodiagnostics, Deep Brain Stimulation, Parkinson’s disease, Essential Tremor, gait, balance disorders, and autonomic dysfunction. He currently runs diagnostic Autonomic function testing. Testing includes Qsweat tests, heart rate-deep breathing tests, Valsalva maneuver tests, tilt table tests, and thermoregulatory sweat tests (TST). Russell would like to learn other modalities within Neurodiagnostics in the future to increase his ability to help diagnose neurological disorders.
