Research and Clinical Interests

Dr. Bob Ohgami is an internationally renowned hematopathologist and recipient of the 2016 Berard-Dorfman Founders Award from the Society for Hematopathology. Following an MD, PhD at Harvard and MIT, he later went on to residency and hematopathology fellowship at Stanford University. There he was an Associate Professor of Pathology, associate program director for anatomic pathology, and director of the molecular pathology core before joining UCSF as Chief of Hematopathology.

As a recognized authority on leukemias and lymphomas, his work spans more than 100 primary journal publications, abstracts, books and chapters. His translational research lab compliments his diagnostic work, pushes the threshold of molecular and computational pathology, and allows for the study of new and known leukemias and lymphomas. Additionally, as a dedicated mentor and teacher, he has received faculty teaching awards at Stanford University in both clinical and anatomic pathology in 2014 and 2016.
