Paul Nghiem, MD, PhD, (he/him/his) is a board certified physician at the Fred Hutchinson Cancer Center, Chair of the UW Department of Dermatology, the George F. Odland Endowed Chair in Dermatology, and a UW professor of Medicine and Dermatology and an adjunct professor in the Departments of Laboratory Medicine and Pathology as well as Oral Health Sciences. Dr. Nghiem oversees the Nghiem Lab, a laboratory focused on the biology of skin cancer. Dr. Nghiem earned his MD and PhD at Stanford. His clinical and research interests include dermatology, Merkel cell carcinoma, melanoma, graft versus host disease and complex skin cancer management in a multidisciplinary team.

Dr. Nghiem holds the following leadership roles in the Dermatology and Skin Oncology community:

  • Director, Skin Oncology Clinical Program, Fred Hutchinson Cancer Center
  • Deputy Director for Seattle Translational Tumor Research, Skin/Cutaneous Oncology
  • Secretary-Treasurer, Society for Investigative Dermatology

Research Interests

A major portion of the Nghiem lab is primarily focused on basic, clinical and translational research aspects of Merkel cell carcinoma. We are involved in several clinical studies on this increasingly common and often lethal skin cancer to determine its basic genetic underpinnings as well as its clinical course and optimal management. The Merkel cell carcinoma Multicenter Interest Group (MMIG), is an international collaborative group, has been formed to leverage diverse resources, interests and expertise to make a difference in this cancer.

A second research interest is focused on skin cancer biology, particularly the molecular mechanism by which the protein kinase ATR mediates an essential cell cycle arrest following DNA damage such as by ultraviolet radiation.  It appears that the skin cancer preventive effect of caffeine is mediated by its inhibition on the ATR-Chk1 pathway, hence eliminating UV-damaged cells from the skin.
