Mitchel B. Harris, MD
Co-Medical Director

Harris’ overarching goal for the center is to bring together individual scientists and clinicians with a common interest in trauma to help streamline research and encourage multi-institutional collaborations. Until the fall of 2016, Harris served as the chief of Orthopaedic Trauma Services at Brigham and Women’s Hospital, where he was awarded the Stepping Strong Distinguished Chair of Orthopedic Surgery. Currently, he is a professor of Orthopedic Surgery at Harvard Medical School, chair of the Department of Orthopedic Surgery at the Massachusetts General Hospital, and the administrative chief of Orthopedic Trauma for Partners HealthCare System. He was a recipient of the International Volvo Award for Low Back Pain Research, has received three Teacher of the Year awards, and received the Hippocrates Society’s Humanitarian Award (2015) from the Brigham and Women’s Physician Organization.

Ali Salim, MD
Co-Medical Director

A leader in trauma care research and support programs for trauma survivors, Salim is focused on the Stepping Strong Center’s mission to advance trauma research, education, community engagement, and policy advocacy. He also serves as a professor of surgery at Harvard Medical School and the chief of the Division of Trauma, Burns, Surgical Critical Care, and Emergency General Surgery at Brigham and Women’s Hospital. As a traumatologist and a surgical intensivist, Salim is a clinically active trauma, general, and critical care surgeon and devotes his time with equal intensity to research, surgical education, and clinical service. His clinical interests focus on the care of acutely ill trauma, emergency surgery, and intensive care unit patients and his clinical research is focused on the care and outcomes of trauma patients, traumatic brain injury, improving the physiology of organ donors, and improving the rate of organ donation.

Matthew J. Carty, MD
Director of Strategy and Innovation

In addition to his role as director of strategy and innovation at the Stepping Strong Center, Carty also serves as director of the Lower Limb Extremity Transplant Program at Brigham and Women’s Hospital and as assistant professor at Harvard Medical School. Carty is focused on reinventing how lower extremity amputations are performed to provide amputees with greater control of prosthetics and restore their limb responsiveness. In collaboration with Hugh Herr, PhD, from the Center for Extreme Bionics at the Massachusetts Institute of Technology, Carty and his team invented the agonist-antagonist myoneural interface (AMI) procedure—a surgical method that preserves the normal signaling between a patient’s ankle-foot muscles and his or her brain. The pioneering surgery makes it possible for an amputee to use a bionic prosthetic that acts like a natural limb.
