About me

Dr. Rony A. François is a dermatologist and dermatopathologist (a specialist in diagnosing skin, hair or nail conditions by examining samples under a microscope). Based on the individual needs of each patient, he develops treatment plans that may include topical and oral medications, skin surgery on a specific area (such as to remove a growth), observation, or a combination of these techniques. He has advanced training in interpreting skin biopsies through microscopic analysis and is particularly interested in caring for patients affected by cancer – whether they had it in the past, are currently living with it, or are on a cancer prevention journey.

In his research, François investigates RAS, the most common kind of cancer-causing gene (oncogene), with the goal of understanding how RAS mutations lead to cancer and developing new ways to target RAS and other genes it works with – potentially curing these cancers. He is particularly interested in targeting gene mutations linked to melanoma as well as lung, colon and pancreatic cancers.

François earned his medical degree and completed a residency in dermatology at the University of Florida, where he also earned a doctorate in molecular and cell biology. At UCSF, he completed a fellowship in dermatopathology.

Outside of work, François enjoys learning about different cuisines, languages and cultures. An audiophile and auditory learner, he enjoys listening to music and singing karaoke.

      Dr was excellent. He did freeze a mole that probably didn't need it but it was precautionary. He trusts my ability to monitor myself since I am data driven. And the care path is collaborative. He didn't fight my input.

      I wish everyone I dealt with in my life was as good at what they did as well as friendly and professional as Dr. Francios.
