Physician Biography

Mary Tomayko M.D., Ph.D., is a physician scientist who brings insight from her inflammation and immunity research to her medical dermatology practice. Dr. Tomayko is an attending physician at Yale-New Haven Hospital, Yale Health and the Yale Primary Care Center, where she directs adult dermatology. She evaluates and treats adults and children with complex dermatologic conditions, including autoimmune and inflammatory disorders such as psoriasis, lupus and autoimmune blistering disease, genetic skin disease and skin cancer. She employs a range of treatment modalities, including systemic immunomodulators, targeted “biologic” agents and phototherapy. Additionally, performs surgical excisions of skin cancers and other skin lesions.

In her research laboratory, Dr. Tomayko works to understand how long-term immunity, so called “memory”, is established and maintained. She has identified molecular pathways required for the development of lasting immunity, including durable antibody titers. She has uncovered unexpected diversity in phenotype and function of the cells that maintain immunity, suggesting exciting new therapeutic approaches to enhance or suppress immunity. She has received funding from the National Institutes of Health, the Arthritis Foundation and the Dermatology foundation. Dr. Tomayko publishes peer-reviewed articles and regularly presents her work at national and international meetings. She is a reviewer for scientific and medical journals and foundations. She is a Medical Editor for Dermatology Focus, a publication that highlights recent advances in the field.

Dr. Tomayko is a director of dermatology education at Yale University School of Medicine. She mentors undergraduate, graduate and medical students in her laboratory, and trains resident physicians and fellows.
