In addition to her clinical training, during her fellowship in multiple sclerosis Dr. Fabian will be obtaining a master's degree in clinical research through the Icahn School of Medicine.


Ilana Katz-Sand, MD is a Sylvia Lawry Fellow at the CGD MS Center. Dr. Katz Sand attended medical school at Columbia University and completed her Internal Medicine internship at Columbia University Medical Center. She currently works alongside physicians and staff in the MS Center caring for patients and participating in research projects. She is  taking part in many clinical studies, for example, projects that are aimed at understanding the relationship of diet and MS, studying the spinal fluid of MS patients, and a study to try and identify outcome measures for arm dysfunction of MS Patients.

Nurse Practitioners

Aliza Ben-Zacharia, CRRN, MSN, ANP-BC, is a board-certified nurse practitioner with years of experience in acute care and rehabilitation. In 2010, she earned a doctorate degree in nursing practice from Case Western Reserve University. Ms. Ben-Zacharia provides direct patient care, follow-up and training for patients and their loved ones and assists in clinical trials. A skilled educator, Ms. Ben-Zacharia has developed educational programs for patients and professionals and has published articles and chapters about multiple sclerosis, disease-modifying agents, symptom management, and palliative care. She is a certified MS nurse, and is a member of the board of the International Organization of Multiple Sclerosis Nurses.

Gretchen K. Mathewson, FNP-BC is a board-certified nurse practitioner with experience in acute and family care. She earned a Master's degree with honors in Family Practice from Columbia University. Ms. Mathewson provides education, counseling, direct patient care, and follow-up for patients and their families. Ms. Mathewson plans to obtain her certification as an MS nurse this spring.

Psychiatry and Social Workers

Dr. Jennifer M. Finkel, MD, Assistant Professor of Psychiatry and Neurology at the Icahn School of Medicine, also serves as the primary psychiatric consultant to the Corinne Goldsmith Dickinson Center for Multiple Sclerosis.

Upon completing her psychiatry residency at NYU/Bellevue, Dr. Finkel embarked upon a fellowship at Mount Sinai which focused on the relationship between medical illnesses and psychiatric disturbances. Her primary focus of study was in MS, and Dr. Finkel has since continued to work closely with the MS community for the past five years.

Dr. Finkel has dual board certification in both Psychiatry and Psychosomatic Medicine. She also serves as Associate Director of the Department of Behavioral Medicine and Consultation Psychiatry.

Tova Epstein, LCSW, and Donna Siegal, LCSW, are social workers for the Corinne Goldsmith Dickinson Center for Multiple Sclerosis. They provide support to patients and their loved ones in matters related to the patient's condition, treatment, and social-service needs.


Patricia Casaccia, MD, PhD is Professor of Neuroscience, Genetics and Genomics, and Neurology. She is the Chief of the Center of Excellence for Myelin Repair at the Friedman Brain Institute at the Icahn School of Medicine. Dr Casaccia's work adopts molecular and cellular techniques to find new therapies for MS. The laboratory focuses on myelin repair with a special emphasis on the effect of aging and gender differences. In addition, her research addresses the mechanism of neuronal damage in patients with MS and she is developing novel screening for the discovery of new therapies to protect the neurons and replace damaged myelin. New methodologies leading to personalized medicine include the generation of neural stem cells from patients' skin, and the analysis of DNA and RNA from the blood of MS patients. Her work is funded by grants from the National Institute for Neurological Disorders and Stroke and by the National Multiple Sclerosis Society.

Gareth John, PhD is Associate Professor at the Icahn School of Medicine and is head of the Beker Multiple Sclerosis Research Laboratories at the Corinne Goldsmith Dickinson Center for MS.

The John laboratory focuses on mechanisms that regulate the formation and repair of lesions in multiple sclerosis. Dr. John and his staff are working under five active grants from the NIH, the National MS Society, pharmaceutical companies, and private benefactors. Their work has been published in Nature Medicine, Journal of Neuroscience, Proceedings of the National Academy of Sciences, and others. Their studies share a common long-term goal of identifying novel therapeutic strategies for inflammatory demyelinating diseases, particularly MS. The research program in the laboratory is also collaborative, in that it allows basic science researchers and physicians to interact and work together towards a common goal.

Matilde Inglese, Md. PhD is an Associate Professor of Neurology, Radiology and Neuroscience at Icahn School of Medicine at Mount Sinai. She received her medical degree magna cum laude from the University of Genoa, Italy and earned a PhD degree from the same university after her formal training in neurology. Her current research, supported by the National Institute of Health, focuses on the development and application of new structural and functional magnetic resonance imaging techniques at high and ultra-high field strength, to study multiple sclerosis and other neurological diseases. This work aims to identify the mechanisms of degeneration which lead to the accumulation of irreversible clinical disability, and to provide surrogate markers to monitor the efficacy of neuroprotective treatments in vivo.
