Amy Fiedler, MD, MSc
Assistant Professor
Surgery
School of Medicine

Fiedler's research focuses on increasing patient access to heart transplantation by improving current techniques for organ preservation and procurement as well as by developing new ones.

Fiedler earned her medical degree at the George Washington University School of Medicine. She completed residencies in general and cardiothoracic surgery at Massachusetts General Hospital, an affiliate of Harvard Medical School. She was in the class of 2020 of the Presidential Leadership Scholars, a program offered through the collaboration of several former U.S. presidents' centers and foundations. She currently serves as surgical director for Team Heart, a nonprofit organization providing cardiac surgery to people in Rwanda.
