Research and Clinical Interests

My primary interests are in Gynecologic pathology, with a focus on molecular aspects of uterine tumors, both endometrial and stromal.  I also serve as a member of the Digital Pathology Working Group to help provide consensus recommendations for digital workstation setups, optimize workflows in the laboratory for slide scanning/distribution, validate scanning quality across various tissue types, and pilot test mock setups for digital sign out. In March of 2020, this work culminated in the the transition of UCSF Pathology to a department-wide, 100% digital workflow.
