  • Dr. Robert Ohgami is an internationally recognized leader in Hematopathology and active translational researcher. He was an undergraduate at Princeton University and an MD/PhD MSTP student in Harvard-MIT’s Health Sciences and Technology Program (HST) working with Dr. Mark Fleming at Children’s Hospital Boston. He went on to complete residency and fellowship at Stanford University in anatomic pathology and hematopathology under Dr. Roger Warnke. He has been a research and clinical faculty member at Stanford University and UCSF and served in leadership positions as a Director of the Molecular Pathology Core, Associate Program Director in Anatomic Pathology, and a Division Chief of Hematopathology. He has authored many peer reviewed publications, abstracts, talks, books and chapters which have been cited more than 5000 times. He is the Hematopathology Associate Editor for the Journal of Molecular Diagnostics, Associate Editor for Frontiers in Oncology, and on the editorial board of several clinical and research journals. In 2016 he was presented with a Berard-Dorfman Founders Award by the then President of the Society for Hematopathology Dr. Sherrie Perkins. A Professor of Pathology at the University of Utah, Dr. Ohgami is a firm advocate for the importance of being an effective mentor and teacher supporting diversity equity and inclusion, and has received several mentorship and teaching awards over the years. Dr. Ohgami’s research interests are in B and T-cell lymphomas, rare diseases such as Castleman disease and blastic plasmacytoid dendritic cell neoplasms, applied artificial intelligence, and technologic innovation.

    Dr. Ohgami is ARUP's founding Vice President and Chief Medical Director for the Institute for Research and Innovation in Diagnostic and Precision Medicine.
