Research Summary

I am Professor of Medicine and Dermatology emeritus on call back at UCSF and staff Endocrinologist at SFVAMC. I continue both my clinical activities and direct a well funded laboratory investigating hormonal regulation of fracture healing and vitamin D and calcium regulation of both skin cancer and wound response.
