Dorry Segev, MD, a transplant surgeon at Johns Hopkins, and Sommer Gentry, PhD, an applied mathematics professor at the United States Naval Academy, are a husband-and-wife team focused on the application of mathematics to health care. Dr. Segev obtained his background in computer science and electrical engineering from Rice University, his medical degree and surgical training from Johns Hopkins, and is currently supported by a grant from the American Society for Transplant Surgeons. Dr. Gentry earned her masters degree in operations research from Stanford University and her doctoral degree in electrical engineering and computer science at the Massachusetts Institute of Technology, under the support of the Computational Science Graduate Fellowship. Drs. Segev and Gentry share a grant from the National Center for Supercomputing Applications.

Daniel Warren, PhD, is an Assistant Professor of Surgery at Johns Hopkins. He has a PhD in Human Genetics from Johns Hopkins and a BS in Biology from Carnegie Mellon University. His research is focused on reducing allograft injury from alloantigen dependent and independent immune responses.

Brigitte Reeb, Administrative Director of the Johns Hopkins Comprehensive Transplant Center, specializes in the integration of clinical, financial and research data to support and optimize operational and business initiatives within healthcare systems. She holds Undergraduate and Masters degrees from New York University.

Robert Montgomery, MD, DPhil, is the Director of the Incompatible Kidney Transplant Program, Chief of the Division of Transplantation, and Director of the Comprehensive Transplant Center at Johns Hopkins. He received his medical education at the University of Rochester, his PhD at the University of Oxford, England in molecular immunology, and his surgical training at Johns Hopkins. Dr. Montgomery 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, and kidney paired donation, and altruistic donor programs.

The predicted impact of Optimized Match on a national KPD program has been reported by these authors in the Journal of the American Medical Association.
