Andrew Horvai

Andrew Horvai is a Medical Educator at the University of California San Francisco (UCSF) School of Medicine, Department of Pathology. With dual training in medicine (M.D.) and biomedical sciences (Ph.D.), he specializes in molecular pathology, cancer research, and genomic profiling of complex tumors.

• Education: B.S. in Biology (1990) from UCLA, M.D./Ph.D. in Biomedical Sciences and Medicine (1998) from UCSD
• Training: General Surgery residency, Pathology residency (2002), and Surgical Pathology fellowship (2003) at UCSF

His research focuses on NF1-associated peripheral nerve sheath tumors, sarcomas, and rare bone/soft tissue neoplasms. Using genomic and spatial transcriptomic profiling, he investigates tumor progression mechanisms, immune microenvironments, and biomarkers for early detection and targeted therapies.

Key publication themes include:

• Molecular characterization of malignant peripheral nerve sheath tumors (2025)
• Epigenetic distinctions in chondroblastoma (2025)
• Metabolic dependencies in primary vs. metastatic tumors (2023)
• Diagnostic challenges in rare tumors like calcifying fibrous tumors and ossifying fibromas

Scientific honors include Phi Beta Kappa (1990), Lucille P. Markey Predoctoral Fellowship (1992), Student Surgical Research Award (2011), and Excellence in Teaching from UCSF's Academy of Medical Educators.
