Dr. Benjamin Philosophe is the surgical director of the Johns Hopkins Comprehensive Transplant Center, as well as the interim chief of the Division of Transplantation in the Johns Hopkins Department of Surgery. He also serves as the lead transplant surgeon at Sibley Memorial Hospital’s Hepatology Multidisciplinary Center.

Dr. Philosophe was the first physician to perform robotic total right and total left hepatic resections in the state of Maryland, has expanded the application of minimally invasive surgical approaches to other hepatobiliary diseases and has improved outcomes and reduced effects of surgery on these patients. Dr. Philosophe is board certified in general surgery and practices out of the Johns Hopkins Hospital in Baltimore, Md., as well as Johns Hopkins Community Physician locations in Bethesda, Md. and Lutherville, Md. He is also affiliated with Suburban Hospital and Howard County General Hospital.

Dr. Philosophe has also been repeatedly named one of America’s Top Doctors and one of America’s Top Doctors for Cancer by Castle Connolly. 

Dr. Philosophe has contributed to numerous publications and presentations. His research interests include uncovering the mechanisms that contribute to transplant rejection and determining characteristics that can be used to better predict donor organ function. He has completed pioneering work in developing a scoring system called the Maryland Aggregate Pathology Index (MAPI), which is used by transplant surgeons worldwide to assess the likelihood of a deceased donor’s kidney function after transplantation. MAPI has increased the utilization of donor kidneys and saved many lives. more

    Research Summary

    Among Dr. Philosophe's research interests are uncovering the mechanisms that contribute to transplant rejection and determining characteristics that can be used to better predict donor organ function. His accomplishments include pioneering work in developing a novel scoring system Maryland Aggregate Pathology Index (MAPI) used by transplant surgeons throughout the world to assess the likelihood of a deceased donor kidneys function after transplantation. This algorithm has increased the utilization of donor kidneys and saved many lives.
