He served his surgical residency at UCLA under Dr. William Longmire and trained in transplantation with Dr. Thomas Starzl at the University of Pittsburgh.

Dr. Busuttil has been a member of the Department of Surgery at UCLA since 1978. In 1984, he established the Liver Transplant Program and has been the Director and Chief Surgeon for more than a decade. Dr. Busuttil has performed over 2000 liver transplants and is internationally known for his surgical expertise and clinical acumen. He has demonstrated a life-long commitment to the care of desperately ill patients, the training of medical students, residents, and surgical fellows; and to the scientific advancement in the field of transplantation surgery. Furthermore, Dr. Busuttil's training program in liver transplantation is currently recognized as the foremost in the world. He has trained both U.S. and international transplant surgeons, many of whom lead liver transplant programs throughout the world.

Dr. Busuttil serves as a reviewer on the editorial boards of many prestigious journals, and is the co-editor of the definitive textbook on liver transplantation, entitled Transplantation of the Liver. He has written over 40 book chapters, 300 abstracts and 350 peer-reviewed scientific publications.
