Professor of Surgery (Transplant)

Biography

David C. Mulligan, MD, is an abdominal organ transplant surgeon performing both living and deceased donor liver, kidney, and pancreas transplants.

He currently serves as Professor of Surgery, Transplantation and Immunology in the Department of Surgery at Yale School of Medicine/Yale New Haven Health System.

His clinical and academic focus surrounds living donor liver transplantation, expanding donation, and working on ways to utilize ex-vivo organ perfusion systems to increase transplantation in the United States.

Dr. Mulligan and his team are testing novel strategies in immunosuppression; improved biomechanical organ preservation methods to reduce ischemia/reperfusion injury and promote regeneration; and working in the field of 3D bioprinting to collaborate in finding ways to grow new organs from stem cell precursors.

He has performed more than 250 living donor transplants and has authored more that 180 publications. He also has served on numerous editorial review boards and presented across the U.S. and internationally.

Dr. Mulligan’s leadership in solid organ transplantation across national and international platforms has grown considerably and he now serves as Past President of the United Network of Organ Sharing (UNOS)/Organ Procurement Transplant Network (OPTN), Member at-large on the Governing Board of the American Association for the Study of Liver Diseases, Past Chair of the Advisory Council on Transplantation (ACOT) to the Secretary of HHS, special government employee for FDA Medical Device Advisory Committee and chair of the Business Practice Committee of the American Society of Transplant Surgeons. He also contributes to the oversight and recommendations regarding the impacts of COVID-19 on solid organ transplantation in the U.S. for both the AASLD and the ASTS.

In these visionary roles, he has led major changes in organ allocation and distribution and will hopefully culminate in substantial increases in organ transplants. Passionate about patient-centered care and building more resilient teams, he makes time to share his enjoyment of spending time in nature, especially near the ocean, with his wife and three children.

Research

Overview

Most recently, I have been heavily involved in national liver allocation and distribution. During my career, I have been extensively involved in scientific and clinical research as well as extensive public policy development and consensus generation. My scientific research began with ischemia/reperfusion injury in livers, immunologic modulation to improve and prolong graft function, and currently working on ex-vivo machine perfusion and 3-D bioprinting for transplantation.

Adding to the scientific research came the opportunity to publish our clinical outcomes, with particular emphasis on Living Donor Liver Transplantation and modulation of immunosuppression.

Since coming to Yale, I have been working with our team to establish successful ex-vivo machine perfusion for solid organ transplantation and utilization of 3-D bioprinting for transplantation.

Most recently, I have become heavily involved with national issues regarding liver allocation and distribution. As the past Chair of the UNOS Liver and Intestinal Transplantation Committee, I led two major national forum meetings sponsored by HRSA as well as multiple webinars, conferences and regional meetings to create consensus around what is best for patients to best utilize the scarce national resources.

Clinical Care

Overview

David C. Mulligan, MD, is an internationally acclaimed leader in organ procurement, distribution, and transplantation—with a focus on living-donor liver transplants, and a professor of surgery at Yale School of Medicine. He also performs pancreas and kidney transplants, as well as surgery for liver and pancreatic disorders and tumors.

Dr. Mulligan, who established the solid organ transplant program at the Mayo Clinic in Arizona before joining Yale Medicine, chose his field partly because of the amazing recoveries patients often make after an organ transplant. “There is nothing more rewarding than to see a patient who was moments from death walk out the door days after surgery with an entirely new outlook on life—and the ability to live a healthy, normal life,” he says.

Organ transplant has evolved rapidly in the last 30 years, and the Yale New Haven Transplantation Center is a leader in performing both kidney and liver transplantations. But, getting organs for all the people who need them has become more difficult, with some patients waiting several years.

Dr. Mulligan believes living-donor transplants are a solution to the organ shortage. He has helped drive a pioneering initiative by Yale Medicine and Yale New Haven Hospital that is creating supportive communities of living donors and providing them with free, lifelong local medical monitoring for any health issues that may arise related to their organ donation.

“If transplant surgeons don’t have these organs, it’s like having one hand tied behind our back, and we are unable to help our patients,” Dr. Mulligan says. “I think we can do better.”

Dr. Mulligan is also a past president of the United Network of Organ Sharing (UNOS)/Organ Procurement Transplant Network (OPTN), and served as division chief for Transplant Surgery at Yale from 2013 until 2022.
