Dr. Greenberg is recognized internationally as an expert in rare autoimmune disorders of the central nervous system. He splits his clinical time between seeing both adult and pediatric patients. He routinely consults on the inpatient units of Zale-Lipshy University Hospital, Parkland Memorial Hospital, and Children’s Health. His research interests are in both the diagnosis and treatment of transverse myelitis, neuromyelitis optica, encephalitis, multiples sclerosis, and infections of the nervous system. He is actively involved in developing better ways to diagnose and prognosticate for patients with these disorders. He has led an effort to improve biorepository development and has created uniform protocols for sample handling and analysis. As part of this initiative, his research has identified novel biomarkers that may be able to distinguish between patients with various neurologic disorders. He also coordinates trials that study new treatments to prevent neurologic damage and restore function to those who have already been affected. He currently serves as the Director of the Neurosciences Clinical Research Center at UT Southwestern and is a Cain-Denius Foundation Scholar.
