    Bio A Bay Area native, Dr. Raja Narayan attended James Logan High School in Union City before going on to Berkeley to obtain his BS in Chemical Biology. He earned his MPH in Biostatistics from Yale before his MD at the University of California, Irvine. Dr. Narayan joined the Stanford General Surgery residency program in 2015.

    Prior to joining Stanford, Dr. Narayan collaborated with the online education platform, Khan Academy, where he developed a library of Physiology videos for the MCAT as well as clinical videos for the NCLEX. While at Yale, Dr. Narayan led a multi-disciplinary team of engineers, pathologists, and surgeons to design, construct, test, and patent a device that preserves intestinal tissue better than the standard of care used to preserve harvested tissue for small bowel transplantation. This work earned him grants from the Yale Center for Engineering, Innovation, and Design as well as the Excellence in Medicine and Physician of Tomorrow awards by the American Medical Association.

    Between 2017-2019, Dr. Narayan spent a research sabbatical with the Hepatopancreatobiliary Surgery service at the Memorial Sloan Kettering Cancer Center studying targets for pancreatic cancer vaccines, genomic correlates of liver tumor biology, and regional differences in biliary tree cancer arising in patients from around the world. Since returning to Stanford in June 2019, Dr. Narayan now leads a team studying the use of artificial intelligence to define donor liver histopathology to predict the risk for early graft failure after transplantation.

    After completion of his residency training, Dr. Narayan plans to pursue a fellowship in Complex General Surgical Oncology.
