Wolff Professor of Renal Diseases and the Director of Transplant Nephrology at Washington University School of Medicine in St. Louis, Missouri until July 2017 when he was recruited to be the inaugural Medical Director and Co-Director of the Comprehensive Transplant Center at The Johns Hopkins School of Medicine. Dr. Brennan received his BA from Cornell College in Iowa with Distinction in Chemistry and his MD from the University of Iowa College of Medicine. He completed his medical internship and residency at the University of Iowa Hospitals and Clinics. He continued his training with clinical and research fellowships at the Brigham and Women’s Hospital/Harvard Medical School.

Dr. Brennan’s research interests are viral infections, induction immunosuppression therapy, pharmacoeconomic and outcome research in transplantation and islet transplantation. He has written more than 200 original publications and has contributed to several textbooks in these areas. He has been on the Editorial Board of Transplantation since 1998, and a Deputy Editor of Transplantation since 2014, an Associate Editor for the American Journal of Transplantation from 2007-2014, the Editor of the Transplant Section of UpToDate since 1999, and Editor in Chief of Nephrology for UpToDate since 2006.

He is board certified in pediatrics, pediatric nephrology and diagnostic laboratory immunology.

For more than three decades, Dr. Jordan has focused his research on the immunology of antibody rejection and development of novel immune modulatory therapies to combat this condition. His work is funded by the NIH and grants from biotechnology firms aimed at developing novel therapies in transplant medicine. He has published more than 360 peer reviewed manuscripts and has 10 patent applications pending.

Dr. Jordan has extensive experience with desensitization for incompatible kidney transplantation and currently has 14 investigator-initiated clinical trials examining novel therapies for desensitization and treatment of antibody-mediated rejection.
