Richard D. Granstein, M.D. is the George W. Hambrick, Jr. Professor and Chairman of the Department of Dermatology at the Weill Cornell Medical College and Dermatologist-in-Chief at the Weill Cornell Campus of the New York-Presbyterian Hospital.  Dr. Granstein's clinical interests include skin disorders resulting from abnormal immune system activity, cutaneous lymphomas and both melanoma and non-melanoma skin cancer.

     Dr. Granstein’s research interests center on regulation of immune processes within the skin, the role of UV radiation in altering immune responses and the relevance of the skin immune system to the development of skin cancer.  Dr. Granstein's laboratory has identified key pathways by which UV radiation contributes to the development of immune suppression and skin cancer.  He also studies the role of nervous system influences and stress on the functioning of the immune system.  He and his colleagues were the first to demonstrate that immune cells within the epidermis have an anatomic relationship with nerves and can be regulated by factors produced by those nerves.

     Dr. Granstein trained in dermatology at Massachusetts General Hospital and Harvard Medical School.  As a research fellow, he studied immunology and tumor biology at the National Cancer Institute and in the Department of Pathology at Harvard.  He joined the Harvard faculty in 1984.  In 1995, Weill Cornell and the New York-Presbyterian Hospital successfully recruited him.  Dr. Granstein is a diplomate of the American Board of Dermatology, a Fellow of the American Academy of Dermatology and has served as an officer, a committee member or on the Board of Directors of numerous medical research and clinical societies including the Society for Investigative Dermatology, the American Society for Photobiology the New York Academy of Medicine, the New York Society of Dermatology and Dermatologic Surgery, the Association for Psychocutaneous Medicine of North America and the American Academy of Dermatology.  He has served as Vice-President of the Society for Investigative Dermatology and is the Immediate Past President of the Association of Professors of Dermatology.
