Multiple Sclerosis Fellowship at The Mount Sinai Hospital

The Multiple Sclerosis Fellowship at the Icahn School of Medicine at Mount Sinai trains clinicians in the diagnosis and management of patients with demyelinating disease. Fellows spend two to three years at The Mount Sinai Hospital, learning about designing clinical trials, analyzing results, and implementing studies. Through our exceptional education and mentorship, graduates receive many employment offers across academic, private practice, and research sectors.

Our fellows gain exposure to a large number of multiple sclerosis (MS) patients of varying ages, disease courses, and severity as our faculty sees approximately 500 new patients and 6,000 follow-up patients each year. Fellows follow patients over the course of their illnesses, monitoring their response to treatments for acute exacerbations and to disease-modifying therapies.

Meet the Director

Under the supervision of attending faculty, fellows at Icahn Mount Sinai are the principal physicians for our multiple sclerosis patients. In addition to doing initial work-ups and following patients, our fellows are responsible for helping to educate neurology interns, residents, and medical students.

Fellows work with an interdisciplinary team of neuroradiologists, advanced practice multiple sclerosis nurse practitioners, a neuropsychologist, social workers, a clinical trial coordinating team, senior multiple sclerosis fellows, and a neuroimaging group. We have affiliations with faculty members in neuroradiology, rehabilitation, urology, psychiatry, oncology, neurophysiology, and neuro-ophthalmology offering a truly multidisciplinary learning experience. Fellows also have access to our state-of-the-art magnetic resonance imaging facilities, including a 7T research magnetic resonance imaging scanner.

Fellows in our program spend a significant portion of their time on research. Our faculty design, implement, and participate in major studies, including those for new agents and approaches to multiple sclerosis and clinically isolated syndrome, and trials of symptomatic therapies and treatment of acute exacerbations. We also serve as the coordinating center for several clinical trials annually.

By working with our faculty, clinical trial coordinators, and monitors, fellows learn all aspects of clinical trial design, implementation, and analysis. You gain an understanding of the regulatory requirements of clinical trials (e.g., interactions with the Institutional Review Board, obtaining an investigational new drug exemption from the U.S. Food and Drug Administration), and have direct experience using the Kurtzke Expanded Disability Status Scale, the Multiple Sclerosis Functional Composite, and other scales often required by various protocols.

Fellows can also utilize the Clinical Curriculum Research Training Grant to earn a Master’s in Clinical Research at Icahn Mount Sinai.

Icahn Mount Sinai selects 2-3 multiple sclerosis fellows each year. To be considered, you should have completed an approved neurology residency or equivalent and be eligible for licensure in the New York State. Fellows must be licensed to practice in New York State before beginning.

Fellows must apply through the Neuroimmunology/Multiple Sclerosis SF Match Program. Applications can be submitted from September 1 to December 1. We conduct interviews with selected candidates in January and February. The rank list submission deadline is Saturday, March 1 and the match results will be made available on March 15.

I chose to train in multiple sclerosis and neuroimmunology at The Corinne Goldsmith Dickinson Center for Multiple Sclerosis at Icahn Mount Sinai because of the unparalleled opportunity to learn from pioneers in the field. Their expertise, multidisciplinary care, and groundbreaking research set the standard for excellence in multiple sclerosis care and treatment. Being in NYC not only provides a dynamic and diverse environment that enriches my training experience, but it also offers an exciting and vibrant lifestyle with its endless cultural attractions, world-class dining, and lively social scene.

Choosing to pursue my fellowship at The Corinne Goldsmith Dickinson Center for Multiple Sclerosis was an easy decision because of the exceptional faculty, program structure, resources, and incredibly diverse demographic that this center serves. I have the opportunity to learn under mentors who are foundational figures in multiple sclerosis clinical trials and participate in cutting-edge research. The diverse patient population helps me incorporate my passion for global health, diversity, and inclusion into the research projects I participate in.
