Clinical Interests

Dr. George Thompson is a Professor of Medicine at the University of California, Davis, School of Medicine (Sacramento, CA) with a joint appointment in the Departments of Medical Microbiology and Immunology, and Internal Medicine, Division of Infectious Diseases. Dr. Thompson specializes in the care of patients with invasive fungal infections and his research interests are in fungal epidemiology, pathophysiology, diagnostics, treatments, and outcomes.

Research/Academic Interests

Dr. Thompson focuses on the fungal diseases caused by Aspergillus, Candida, and Coccidioides spp.  These fungi are of both regional and global importance.  Aspergillus infections continue to emerge in new patient populations (eg COVID19), Candida spp are the 4th leading cause of bloodstream infections across the world and carry substantial morbidity and mortality, and coccidioidomycosis affects over 450,000 people per year within the Southwestern United States.  Our studies focus on the evaluation of new antifungal agents, the pathophysiologic mechanisms of antifungal therapy, including both the development of resistance and the biologic underpinnings of adverse drug reactions.  

He served as the co-chair of the National Academy of Sciences Symposium on Coccidioidomycosis in the fall of 2022, and as an advisor to the World Health Organization (WHO) for fungal priority pathogens.  He has additionally served on multiple international guidelines which are highly utilized by clinicians globally.  He currently is the chair of the Mycoses Study Group Education Committee – and is responsible for the development of fungal educational content to practitioners globally and the design of pivotal clinical trials.  He has served on both the CDC and the National Institute of Allergy and Infectious Diseases Special Emphasis Panels as a grant reviewer and on the FDA Antifungal and Coccidioidomycosis Advisory committees.  He has also been a congressional consultant for the Valley Fever Task Force, and the Congressional Pasteur and Forward Acts focused on antifungal and antibacterial resistance.
