Samuel Hwang M.D., Ph.D.
Dr. Hwang is a board-certified dermatologist with extensive training as a physician scientist. He has strong clinical and basic science interest in immunological diseases of the skin, including psoriasis, and in the biology of skin cancers, including melanoma and cutaneous T cell lymphoma. Starting as an Investigator and then Senior Investigator at NIH, Dr. Hwang has had over 15 years of experience in the field of leukocyte and cancer cell trafficking and has had a long standing interest in the role of chemokine receptors, including CCR6 and CXCR4 in immune cells as well as cancer cells. In 2008 he was appointed the Thomas J. Russell Family and Community Dermatologists Chair and Professor of Dermatology at the Medical College of Wisconsin. He has published more than 65 original and review articles in the Journal of Experimental Medicine, Cancer Research, Journal of Immunology, Journal of Investigative Dermatology, Archives of Dermatology, and Proceedings of the National Academy of Science (USA). In 2016, he was elected to the Board of Directors of the Society for investigative Dermatology and serves as section editor for the Journal of Investigative Dermatology and the Journal of Dermatological Sciences. He was elected by his peers to the American Society for Clinical Investigation in 2007 and has lectured internationally and nationally.
