Raymond Cho, MD, PhD


Dr. Raymond Cho is a dermatologist and geneticist who treats a wide range of skin conditions. In his research, he studies the patterns in which DNA changes accumulate across the genome, during the development of skin and other cancers.

Cho earned a medical degree and Ph.D. in genetics at Stanford University School of Medicine and completed a residency in dermatology and a fellowship in molecular medicine at UCSF. He received a Career Development Award from the Dermatology Foundation and was an American Skin Association Abby S. & Howard P. Milstein Research Scholar in Melanoma. His research is funded by the National Institutes of Health and as a Samsung Biotechnology Scholar-in-Residence. Cho is an associate clinical professor of dermatology at UCSF.
