Dermatopathology Fellowship

Dr. McNiff received her M.D. from the University of Vermont College of Medicine, and trained in Anatomic and Clinical Pathology at the University of Virginia Health Sciences Center. After completing a fellowship in dermatopathology at the Medical College of Virginia in 1992, Dr. McNiff joined the faculty at the Yale University School of Medicine. Dr. McNiff’s interests and publications are focused on general clinicopathologic correlations in dermatopathology, mycosis fungoides, animal models of lupus erythematosus and graft vs. host disease, and immunofluorescence techniques in dermatopathology. She is a frequent invited speaker at national and international meetings, and is the past President of the American Society of Dermatopathology.

Marcus Bosenberg MD, PhD, is a physician scientist who directs a leading melanoma research laboratory, is Co-Leader of the Cancer Immunology Program of Yale Cancer Center, Director of the Yale Center for Immuno-Oncology, Contact PI of the Yale SPORE in Skin Cancer,  Director of the Center for Precision Cancer Modeling, and is a practicing dermatopathologist at Yale Dermatopathology through Yale Medicine.In his research, Dr. Bosenberg studies factors that regulate anti-cancer immune responses. His laboratory has developed several widely utilized mouse models in order to study how melanoma forms and progresses, to test new cancer therapies, and how the immune system can be stimulated to fight cancer. He works to translate basic scientific findings into improvements in cancer diagnosis and therapy. He has published over 200 peer-reviewed articles and is a member of the Yale Cancer Center Executive Committee.Dr. Bosenberg mentors undergraduate, graduate, medical, and MD-PhD students in his laboratory, teaches at Yale School of Medicine, and trains resident physicians, fellows, and postdoctoral fellows.

William Damsky, M.D., Ph.D. is a physician-scientist who uses basic and translational approaches to understand mechanisms of skin disease. In clinical practice, he specializes in medical dermatology and dermatopathology with a specific focus in cutaneous granulomatous disorders (sarcoidosis and granuloma annulare). Dr. Damsky is an attending physician at Yale-New Haven Hospital, Yale Health Center, the VA Veteran's Hospital, and Cornell Scott Hill Health Center. Dr. Damsky provides care for both adult and pediatric patients.Dr. Damsky provides care for patients with all dermatologic conditions and he has special interest in:sarcoidosisgranuloma annularepsoriasisatopic dermatitis (eczema)acne and hidradenitis suppurativaother cutaneous granulomatous disorders such as necrobiosis lipodicaother inflammatory skin disorders such as lichen planusskin cancerDr. Damsky uses a wide variety of treatment modalities including retinoids including isotretinoin, phototherapy, systemic immunomodulatory agents, "biologic" agents to treat psoriasis, atopic dermatitis, and other disorders, and Janus kinase (JAK) inhibitors.In his research, Dr. Damsky is using various pre-clinical and translational approaches to study inflammatory skin diseases as well as melanoma. Dr. Damsky is leading a clinical trial in sarcoidosis and granuloma annulare. Dr. Damsky has published over 50 peer-reviewed articles. His research is supported by the Dermatology Foundation, the Skin Cancer Foundation, and Pfizer. He was received the Young Investigator Award from the American Academy of Dermatology in 2020 for his research in sarcoidosis. Dr. Damsky completed his undergraduate, M.D., and Ph.D. degrees the University of Vermont. He completed an internship in Internal Medicine and residency in Dermatology at Yale. Dr. Damsky also completed an N.I.H. funded Research Fellowship in Investigative Dermatology and served as Chief Resident during this time.

Dr. Christine Ko is Professor of Dermatology and Pathology. She is board certified in dermatology with a specialty certificate in dermatopathology. Most of her time is spent in the Division of Dermatopathology, where she renders diagnoses for skin biopsies, sent in to Yale from Yale Dermatology Associates and other dermatology practices in Connecticut.  Dr. Ko currently specializes in Transplant Dermatology, providing care for patients with organ transplants who are generally on immunosuppressive medications and are at higher risk for skin cancer.  Dr. Ko received her AB at Princeton University and MD from New York University School of Medicine. She completed internship at UCLA, and her dermatology residency at University of California, Irvine.  Her research focuses on skin cancer, particularly squamous cell carcinoma and keratoacanthoma, in collaboration with researchers in the Department of Genetics and the Division of Dermatologic Surgery.

Peggy Myung is interested in hair follicle development and regeneration. Currently, she studies hair follicle development in mice and has a focus on how the dermal niche regulates hair follicle cell fate decisions. In particular, her work is centered on understanding the epithelial-mesenchymal interactions that regulate epithelial growth and differentiation in an effort to re-purpose these same molecular mechanisms to suppress aberrant growth in carcinogenesis.
