Iwei Yeh, M.D., PhD DermatopathologistI graduated from Harvard College in 1997 with a degree in Biochemical Sciences.  Then I returned to my native Bay Area to attend medical school at Stanford University.  I finished my studies at Stanford in 2006 with an MD and a PhD in Biomedical Informatics.  I completed my internship at Santa Clara Valley Medical Center in San Jose, CA and my dermatology residency at the University of Washington in Seattle, WA.  During my residency I became interested in the genetics of melanocytic neoplasms and began a research path in the laboratory of Boris Bastian.  I completed my dermatopathology fellowship at UCSF in 2011.  After a brief stint at Memorial Sloan Kettering Cancer Center, I returned to UCSF as a faculty member.

I currently practice diagnostic dermatopathology as well as basic and pre-clinical research in the field of melanocytic neoplasia.  There are many exciting new technologies that we can harness to improve diagnosis and treatment for our patients and understand the varied mechanisms that lead to skin cancer.
