Dr. Robert A. Montgomery, MD, DPhil, FACS, is the inaugural recipient of the Margery K. and Thomas Pozefsky Endowed Professorship in Kidney Transplantation. He received his doctor of medicine with Honor from the University Of Rochester School Of Medicine. He received his  doctor of philosophy from Balliol College, The University of Oxford, England in molecular immunology. In 2007 he was awarded an honorary doctor of science from his Alma Mater, St Lawrence University. Dr. Montgomery completed his general surgical training, multi-organ  transplantation fellowship and post-doctoral fellowship in human molecular genetics at Johns Hopkins.

Dr. Montgomery was part of the team that developed the laparoscopic procedure for live kidney donation, a procedure that has become the standard throughout the world. He and the Hopkins team conceived the idea of the Domino Paired Donation and the Hopkins protocol for desensitization of incompatible kidney transplant patients. Dr. Montgomery participated in the first chain of transplants started by an altruistic donor. He led the team that performed the first 2-way domino paired donation, 3-way paired donation, 3-way domino paired donation, 4-way paired donation, 4-way domino paired donation, 5-way domino paired donation, 6-way domino paired donation, 8-way multi-institutional  domino paired donation, and co-led the first 10-way open chain. He is credited in the 2010 Guinness Book of World Records with the most kidney transplants performed in one day. Dr. Montgomery is considered a world expert on kidney transplantation for highly sensitized and ABO incompatible patients. His work with patients in these programs has been featured on the Today Show, Good Morning America, the CBS, ABC and NBC Evening News, CNN, The Discovery Channel, USA Today, and the front page of The New York Times, Wall Street Journal, and The Washington Post.

Dr. Montgomery has received important awards and distinctions including a Fulbright Scholarship and a Thomas J. Watson Fellowship and  memberships in the Phi Beta Kappa and Alpha Omega Alpha academic honor societies. He has been awarded multiple scholarships from The American College of Surgeons and The American Society of Transplant Surgeons. The National Kidney Foundation of Maryland has recognized his contributions to the field of transplantation with the Champion of Hope Award and the National Kidney Registry recognized him with the Terasaki Medical Innovation Award. more

    Research Summary

    Dr. Montgomery is a co-principal investigator for an NIH/ITN sponsored tolerance clinical trial for simultaneous donor bone marrow and live donor kidney transplantation. He runs multiple investigator initiated clinical trials of novel desensitization therapies. His research interests include mechanisms underlying the immunomodulatory effect of plasmapheresis, stem cell therapy for highly sensitized patients, and gene and cell based therapies in transplantation.

    Clinical Trials:

    ACCEPTOR Clinical Trial for Kidney Transplant Recipients

    The purpose of this study is to find out if the study treatment will allow people to accept their new kidney and be able to stop taking anti-rejection medications.
