Susan Gauthier
Director of Clinical Research
Dr. Susan Gauthier received her D.O. degree from the Philadelphia College of Osteopathic Medicine. After completing her neurology residency at the Boston University Medical Center, where she served as Chief Resident, Dr. Gauthier was a recipient of a three-year National Multiple Sclerosis Society (NMSS) clinical trial training fellowship, which she completed at the Brigham and Women’s Hospital in Boston, and received an M.P.H. from the Harvard School of Public Health. Upon her joining the clinical staff at the Weill Cornell Multiple Sclerosis Center (WCMSC) at Weill Cornell Medical College, she was a recipient of the Feil Family Clinical Scholar Award.
Dr. Gauthier established the clinical research infrastructure at the WCMSC, which includes a highly productive collaboration with the department of radiology. Her research is focused on the translation of early-stage imaging techniques to explore biological mechanisms at play in multiple sclerosis, with a specific interest in quantification of myelin and inflammation. Dr. Gauthier has received research awards from the NMSS and various pharmaceutical companies. Her work has been recently recognized through frequent presentations at international meetings and numerous publications in peer-reviewed journals. Dr. Gauthier is frequently an invited speaker at imaging-based international meetings and has developed herself as a leader in the field of MS quantitative imaging. She is a member of the editorial board of the Journal of Neuroimaging and serves a scientific reviewer for the NMSS. Dr. Gauthier has mentored a number of postdoctoral candidates, residents and research fellows as part of her active research program.

Amit Kohli
Amit Kohli, M.D., is a Clinical Attending and Assistant Professor of Clinical Neurology at New York Presbyterian/Weill Cornell Medical College specializing in Multiple Sclerosis and related autoimmune disorders. The goal of his practice is to provide compassionate care which places the patient as a person first while delivering the highest levels of expertise available in diagnostic and therapeutic strategies. Having trained extensively with a focus on autoimmune conditions of the central nervous system, Dr. Kohli’s vision for holistic care is based on years of experience in finding solutions for both the everyday and long-term needs of patients with autoimmune and demyelinating diseases. His clinical and research focus is on the application of cutting-edge strategies and tools for the diagnosis of conditions such as Multiple Sclerosis (MS), NMO, MOG Antibody Disease, ADEM, Optic Neuritis, Transverse Myelitis, Neurosarcoidosis, and others.
Dr. Kohli earned his undergraduate degree in biology with a concentration in neuroscience from the University of Chicago, and his M.D. from the Zucker School of Medicine at Northwell Health. He completed his residency in Neurology at The Mount Sinai Hospital on the upper east side of New York and continued on to complete his fellowship in Multiple Sclerosis at the Corrine Goldsmith Dickinson Center for MS at Mount Sinai. While at the CGD Center, Dr. Kohlipracticed under the mentorship of Drs. Fred Lublin, Aaron Miller, Stephen Krieger, and others, helped to run clinical trials in progressive MS, and researched diagnostic strategies to improve the detection of cortical lesionsin Multiple Sclerosis, which were presented nationally.
At Weill Cornell’s Judith Jaffe Multiple Sclerosis Center, Dr. Kohli engages in research on state-of-the-art imaging techniques to identify and treat inflammation in MS. He plans to participate in clinical trials to find better treatment options for patients living with Multiple Sclerosis.

Jai Perumal
Director of Clinical Operations at Weill Cornell MS Center
Director of MS Service at NewYork-Presbyterian Queens
Dr. Jai S. Perumal received her medical degree from Stanley Medical College in India. She completed her internal medicine internship and neurology residency at Wayne State University in Detroit, Michigan, where she was chief of neurology. She then completed her two-year clinical neuro-immunology fellowship including multiple sclerosis at Wayne State University. She is a recipient of the Sylvia Lawry Fellowship of the National Multiple Sclerosis Society. She is a Feil multiple sclerosis clinical scholar at Weill Cornell Medical College. She has presented at several neurology meetings and conferences and has been published in several peer-reviewed journals. Dr Perumal is board-certified for neurology with additional specialized training in demyelinating disorders including multiple sclerosis.
Dr. Perumal's research interests include disease phenotypes in multiple sclerosis, MS therapeutics and ethnic influences on disease characteristics. She sees patients with MS, neuromyelitis optica, transverse myelitis, CNS vasculitis, neuro-sarcoidosis, autoimmune encephalitis and central nervous system manifestations of systemic autoimmune diseases including SLE.
