Welch Professor of Surgery at Harvard Medical School and Chief of the Transplantation Unit at the Massachusetts General Hospital.  After graduating summa cum laude from Regis College in Denver, Dr. Cosimi earned his M.D. degree magna cum laude from the University of Colorado. He served his surgical residency at the MGH where he also trained in transplantation.  Dr. Cosimi has demonstrated a life-long commitment to scientific advancement in the field of transplantation and surgery. He has had a special interest in highly selective suppression of transplant immunity.  He was the first to demonstrate in 1980 the efficacy of OKT3 monoclonal antibody, a drug still used today, for treatment of allograft rejection. He has trained over 35 clinical transplant fellows and many of the surgeons currently using the non-human primate transplant model in the U.S. Most recently, Dr. Cosimi's efforts have been directed towards defining an immunosuppressive approach that provides donor-specific tolerance of the transplant.  Dr. Cosimi is on the Editorial Board of many prestigious surgical and transplantation journals and is the co-editor of the definitive textbook, Transplantation.  He has published over 50 book chapters and 350 peer-reviewed scientific reports.  He is a member of many national and international surgical and transplantation societies and has held key executive council or committee positions in many of these.  He's currently immediate Past-President of the New England Surgical Society, President of the American Society of Transplant Surgeons as well as President of the 2006 World Transplantation Congress which will be held in Boston in July of this year.  He also currently on the Scientific Advisory Boards for the American Liver Foundation, the Massachusetts Kidney Foundation, and several biotechnology research foundations.
