James Grenert

James Grenert is a Professor in the Department of Pathology at the University of California, San Francisco (UCSF) School of Medicine. His research focuses on molecular pathology, cancer genomics, and precision oncology, with a particular emphasis on hepatocellular carcinomas, neuro-oncological tumors, and urothelial malignancies. He employs next-generation sequencing (NGS) to characterize tumor genetics, identify actionable mutations, and improve diagnostic accuracy.

His recent publications highlight work on

• genomic profiling of liver and brain tumors
• APOBEC mutational signatures in bladder cancer
• HER2 overexpression in urothelial carcinoma
• transmission of cancer via organ transplants

He collaborates extensively with UCSF colleagues like Arie Perry, Jessica Van Ziffle, and Sanjay Kakar, contributing to advancements in tumor classification, germline mutation analysis, and targeted therapy applications.
