Sandy Feng, MD, PhD
Professor
Surgery
School of Medicine

In her research, Feng studies transplantation tolerance, a transplant recipient's ability to maintain normal organ function with minimal or no use of immunosuppressive drugs. With funding from the National Institutes of Health, she has led several multicenter clinical trials to study tolerance in both adult and pediatric liver transplant recipients.

Feng is a graduate of Harvard College, where she received the prestigious Marshall Scholarship. She completed a doctorate in molecular biology at the University of Cambridge and earned her medical degree at Stanford University School of Medicine. She completed a general surgery residency at Brigham and Women's Hospital, followed by a transplant fellowship at UCSF.

Feng has held leadership positions in prominent professional societies and with the United Network for Organ Sharing. She has organized several national conferences addressing issues critical to the transplantation community, serves on the editorial board of the New England Journal of Medicine and is the editor-in-chief for the American Journal of Transplantation.
