Dr. Gerald Haase is a Clinical Professor of Surgery at the University of Colorado School of Medicine and Children’s Hospital Colorado. Dr. Haase has been active in clinical research trials for three decades including collaborations in the design of central venous access devices, applications of intra-operative radiation therapy for treatment of pediatric tumors, evaluation of technical surgical innovations in adult and childhood cancer, and development of novel strategies for antioxidant micronutrient therapy for war fighter protection, against hazardous exposures, for certain chronic conditions, and for optimal health. He received a B.A. degree from Johns Hopkins University, his M.D. degree from Tufts University School of Medicine and was awarded graduate honors in medical research. His post-graduate training was at the University of Colorado, the Children’s Hospital Medical Center, Boston, and the Children’s Hospital, Columbus, Ohio. In clinical practice, he was board certified in general surgery, pediatric surgery and critical care. He was Chairman of Pediatric Surgery at Children’s Hospital Colorado, and consultant pediatric surgeon to the Department of the Army. Dr. Haase served as vice-chairman of the Children’s Cancer Group, a cooperative research consortium of the National Cancer Institute. He was a member of the National Board of Directors of the American Cancer Society and its representative to the Alliance for Childhood Cancer. He is the author or co-author of 175 scientific publications, holds twelve U.S. patents for antioxidant micronutrient therapy and been the recipient of clinical research grants and contracts funded at a multi-million dollar cumulative level.
