Dr. Viswanathan is a member of the Massachusetts ADRC and a staff neurologist at the Stroke Service  and Memory Disorders Unit at the Massachusetts General Hospital. He received his MD, PhD in medicine and molecular genetics from Emory University, and was trained in internal medicine at the Beth Israel Deaconess Medical Center prior to his residency program in vascular neurology at the Massachusetts General Hospital and the Brigham and Women's Hospital.
Dr. Viswanathan served as a clinical research fellow with Professors Marie-Germaine Bousser and Hugues Chabriat at the Hôpital Lariboisière  in Paris from 2005-2006, and his group actively collaborates with colleagues at the Hôpital. Dr. Viswanathan's research interests include studying the contributions of stroke and vascular risk factors to dementia.
