Summary of Research Studies:
Our laboratory studies the biology of lysosomal enzymes, genes and diseases. Two of the main projects in the lab are focused on the enzymes acid sphingomyelinase (deficient in Types A & B Niemann-Pick disease) and acid ceramidase (deficient in Farber Lipogranulomatosis or Farber disease). We integrate the tools of molecular biology, biochemistry, pharmacology and other disciplines to understand the pathogenic mechanisms causing these disorders and to develop new therapies. Our lab is responsible for the gene cloning of both enzymes, identification of the first mutations causing the human diseases, production and characterization of both human recombinant enzymes, and the construction of the first animal models for the human diseases. This work has led to the first enzyme replacement therapy clinical trials for Niemann-Pick disease (collaboration with the Genzyme/Sanofi), institution of the first genetic screening program for this disorder throughout the world, and the formation of a new company (Plexcera Therapeutics) to develop enzyme therapy for Farber disease. We continue to work closely on the role of acid sphingomyelinase and acid ceramidase in lipid-mediated cell signaling and to understand how these enzyme and genes are involved in various other disease pathologies, including common disorders such as type II diabetes and monogenic disorders such as cystic fibrosis. We also collaborate on the development of new therapies for another group of lysosomal storage disorders, the mucopolysaccharidoses.

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
Physicians who provide services at hospitals and facilities in the Mount Sinai Health System might not participate in the same health plans as those Mount Sinai hospitals and facilities (even if the physicians are employed or contracted by those hospitals or facilities).
Information regarding insurance participation and billing by this physician may be found on this page, and can also be obtained by contacting this provider directly. Because physicians insurance participation can change, the insurance information on this page may not always be up-to-date. Please contact this physician directly to obtain the most up-to-date insurance information.
Insurance and health plan networks that the various Mount Sinai Health System hospitals and facilities participate in can be found on the Mount Sinai Health System website.
