Multiple Sclerosis Fellowships

Mass General Brigham Pediatric Multiple Sclerosis Center at Massachusetts General Hospital annually offers several fellowship opportunities.

Clinical Fellowship Program

Combined Harvard Pediatric Multiple Sclerosis and Related Disorders Fellowship

Fellows rotate through the Mass General Brigham Pediatric MS Center at Massachusetts General Hospital for one to two years (with Tanuja Chitnis, MD), with additional rotations at Children’s Hospital Boston (with Mark Gorman, MD) and the adult Mass General Brigham MS Center (with Tanuja Chitnis, MD). 

Fellows will learn about pediatric MS, neuromyelitis (NMO), and related demyelinating disorders (DD) and will build a knowledge base regarding MS, NMO, and DD clinical care. Through exposure to adult patients with MS, they will understand the long-term consequences of MS, including pediatric-onset MS. In addition, fellows will be exposed to cases of autoimmune encephalopathy, opsoclonus-myoclonus, and other neuroimmunology disorders. 

Fellows will participate in direct supervised MS patient care and multidisciplinary care including a child psychiatrist, neuropsychologist, family counselor, and nurse. Fellows will also participate in a research project tailored to their interests, through resources available within the program including a clinical database, ongoing neuroimaging and neuroimmunology studies, clinical trials, and access to a national pediatric demyelinating diseases database.

This fellowship is GME accredited by Mass General Brigham.

Clinical Research Fellowship Program

Clinical research fellows are offered a rich research environment with exposure to ongoing clinical research in diagnosis, diseases course, response to treatment, clinical trials, neuroimmunology, and neuroimaging in pediatric MS, NMO, and related demyelinating diseases. The research project depends on current study needs and may be tailored to the fellow’s interests and skills. Access to a comprehensive local and national database on pediatric demyelinating diseases may be utilized. Observation of clinical care may be incorporated into this fellowship.

External sources of funding are an asset.
