Dr George R. Thompson completed his medical degree at the University of Missouri and his internal medicine residency and infectious disease fellowship at the University of Texas Health Sciences Center in San Antonio and is a member of Alpha Omega Alpha. He is a Professor of Medicine at the University of California, Davis, School of Medicine, with a joint appointment in the Departments of Internal Medicine, Division of Infectious Diseases and Medical Microbiology and Immunology and co-director of the UC-Davis Center for Coccidioidomycosis.
Dr Thompson specializes in the care of patients with invasive fungal infections and has research interest in fungal diagnostics and host immunogenetics. His current research focuses on the host-pathogen interaction of humans and both Coccidioides spp. (the agent of “Valley Fever”), and Cryptococcus spp. Dr Thompson has substantial expertise in the care of patients with fungal diseases and co-chairs the Mycoses Study Group Education and Research Consortium Education Committee, which is responsible for the dissemination of materials and knowledge to clinicians across the country to improve the care of patients with fungal infections. He has also been appointed to the Coccidioidomycosis Study Group and the Infectious Diseases Society of America (IDSA) Journal Club, providing editorials in its monthly internationally disseminated IDSA Newsletter.
Professor of Pathology & Laboratory Medicine
and Medicine/Infectious Diseases
Director, Fungus Testing Laboratory
University of Texas Health Sciences Center at San Antonio
Nathan P. Wiederhold, PharmD, is Professor of Pathology and Laboratory Medicine at the University of Texas Health Science Center at San Antonio. He earned his bachelor’s degree in biology and his doctorate in pharmacy at the University of Texas at Austin, and completed residency training at Barnes-Jewish Hospital, St. Louis, and a fellowship in medical mycology at the University of Houston and UT MD Anderson Cancer Center. He is currently director of the Fungus Testing Laboratory at UT Health San Antonio.
Dr Wiederhold’s research is focused on trends in antifungal resistance, new mechanisms of drug resistance in fungi, and the evaluation of novel agents under development for the treatment of invasive fungal infections, concentrating on the preclinical evaluation of investigational therapeutic modalities and diagnostic technologies for the diagnosis and treatment of fungal infections. This includes both in vitro assessment for activity against a wide range of fungal pathogens, such as multi-drug resistant clinical isolates, and in vivo models of invasive fungal infections. This work, supported through NIH/NIAID contracts and grants from industry, involves close collaboration with other researchers in the Departments of Microbiology and Immunology, Medicine/Infectious Diseases, and Pathology. Dr Wiederhold’s laboratory also serves as the central mycology laboratory for several clinical trials and post-marketing studies.
