Biography

Dr. Sandy Feng is a transplant surgeon who performs liver, kidney and pancreas transplants.

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.

Dr. Feng was elected to be a member of the National Academy of Medicine in 2023.

Research Narrative

Dr. Feng's research interest focuses on transplant immunology, with a particular focus on determinants of organ tolerance. She is also investigating novel immunosuppressive regimens and pursuing immunosuppression withdrawal in selected liver transplant recipients. By studying the immune profiles of transplant patients who are successfully weaned from immunosuppressants, she and her group hope to predict prospectively which patients may be good candidates for immunosuppression withdrawal.

Research Interests

  • Immunosuppression Withdrawal for Stable Pediatric Living Donor Liver Transplant Recipients
  • Immunosuppression Withdrawal and Identification of a Profile Predictive of Tolerance
  • Defining the Optimal Immunosuppression for Specific Transplant Settings
  • Expanded Criteria Donors
  • Novel Immunosuppression Strategies for Liver Transplantation
  • Strategies to Decrease Ischemia Reperfusion Injury to Improve Early Graft Function after Kidney Transplantation
  • Improving Long-term Outcomes for Liver Transplant Recipients
