CameronAndrew M. Cameron, M.D., Ph.D.
Andrew Cameron is an assistant professor of surgery in the Comprehensive Transplant Center. He attended Johns Hopkins Medical School and trained in surgery at the Massachusetts General Hospital in Boston. He pursued fellowship training at UCLA, studying liver transplantation, and now focuses on hepatobiliary surgery. His clinical interests include end stage liver disease and hepatocellular cancer. Cameron runs a basic science laboratory studying molecular aspects of hepatitis C, focusing on developing RNA technology to design novel drugs for prevention of viral recurrence after liver transplant.

MaleyWarren R. Maley, M.D.
Warren R. Maley is an associate professor of surgery at The Johns Hopkins University School of Medicine and the director of liver transplantation at The Johns Hopkins Hospital. Twenty years ago, when he first arrived at Johns Hopkins to complete his surgical internship, Maley had already attained recognition as a medical scholar and had received national honors for excellence in the medical profession. He finished his residency at Johns Hopkins and later completed a gastrointestinal and transplant fellowship at this hospital. He continued to hone his surgical technique at institutions such as the John Radcliffe Hospital in Oxford, England, Allegheny Surgical Associates in Pittsburgh and the Louisiana State University’s Health Sciences Center in Shreveport. Over the years, he has become known for his skillful performance in the operating room and has helped Hopkins train countless young transplant fellows to become outstanding surgeons. His research and academic work focuses on organ preservation and clinical outcomes. He is a member of the Association for Academic Surgery as well as the American Society of Transplantation.

MelanconJ. Keith Melancon, M.D. 
J. Keith Melancon is an assistant professor of medicine at The Johns Hopkins University School of Medicine and the director of kidney and pancreas transplantation and clinical transplantation research at The Johns Hopkins Hospital. Melancon is originally from Louisiana and received his medical education and surgical training from Tulane University. He completed a multi-organ transplantation fellowship at the University of Minnesota. The Minnesota transplant program is internationally acclaimed for its work in pancreas and islet cell transplantation. Melancon’s specialties include kidney, liver and pancreas transplantation, pancreas islet and stem cell transplantation, and laparoscopic kidney donation. Among his research interests are minimizing immunosuppression, transplant organ tolerance, racial differences in outcomes of organ transplantation, stem cell transplantation and islet transplantation.

MontgomeryRobert Montgomery M.D., Ph.D.
Robert A. Montgomery is an associate professor of surgery at The Johns Hopkins University School of Medicine, and director of the Incompatible Kidney Transplant Program, chief of the Division of Transplantation, and director of the Comprehensive Transplant Center at The Johns Hopkins Hospital. He received his medical education at the University of Rochester, where he was the valedictorian of his class. He received his Ph.D. at the University of Oxford, England, in molecular immunology. He received further postdoctoral education in human molecular genetics and completed both his general surgical and multi-organ transplantation training at Johns Hopkins.

He has been involved in the development of innovative approaches to expanding live donor renal transplantation, including the laparoscopic donor nephrectomy, positive crossmatch and ABO incompatible transplantation, paired kidney exchange, and altruistic donor programs. He was part of the team that performed the world’s first live donor kidney removal using minimally invasive techniques and the first reported paired kidney exchange in the United States. In 2003, Dr. Montgomery led the team that performed the first triple paired kidney exchange. He has lectured extensively throughout the world about the Hopkins’ protocol for desensitizing patients with immunologic incompatibilities with their donors.

His other clinical interests include the use of expanded-criteria donors and pulsatile perfusion pumping to preserve and rescue these organs. He is the principle investigator on a Health and Human Services grant for enhancing the utilization of expanded-criteria donor organs. Montgomery runs an NIH-funded laboratory that is focused on the mechanisms underlying the immunomodulatory effect of plasmapheresis, as well as gene- and cell-based therapies for ameliorating ischemia/reperfusion injury.

Li-MingSuLi-Ming Su, M.D.
Li-Ming Su is an associate professor of urology at The Johns Hopkins University School of Medicine and director of laparoscopic and robotic urologic surgery in Hopkins’ Brady Urological Institute.  He joined the urology staff at Johns Hopkins after completing his urology residency at New York Presbyterian Hospital-Cornell University Medical College and fellowship training in endourology (specializing in laparoscopy, robotics and stone disease) at Johns Hopkins. His main clinical interests include minimally invasive techniques for the treatment of kidney cancer and prostate cancer. His areas of surgical specialty include laparoscopic partial nephrectomy, laparoscopic radical nephrectomy, nerve-sparing robotic-assisted laparoscopic radical prostatectomy, laparoscopic pyeloplasty, retroperitoneal lymph node dissection and donor nephrectomy.

TanMiguel Tan, M.D.
Miguel Tan is an assistant professor of surgery in the Division of Transplantation. He joined the Comprehensive Transplant Center as a surgeon in the kidney/pancreas transplant program in December 2005. He brings extensive clinical experience to his role at Hopkins, having trained for over 10 years at Canada’s McGill University and the McGill Royal Victoria Hospital Research Institute. Most recently, he comes to Hopkins from a transplant surgery fellowship at the University of Minnesota. His clinical and research interests include pancreas and islet cell transplantation, kidney transplantation, clinical immunosuppression, steroid-free protocols, and novel immunosuppressive agents.

SegevDorry Segev, M.D.
Dorry Segev is an assistant professor of medicine at the Johns Hopkins University School of Medicine. During his training at Johns Hopkins over the past 14 years, Segev had made numerous, significant contributions, including development of a mathematical model to facilitate a nationwide paired kidney exchange program. Segev’s research focuses on medical data modeling and simulation, analysis of large health care data sets, and clinical study. His clinical focus is on incompatible organ transplantation as well as kidney and liver transplantation.
