Program Faculty

Richard A. Calderone, PhD

Dr. Richard Calderone, PhD, is Chair of the Department of Microbiology and Immunology and Director of the MS Degree Program in Biomedical Science Policy & Advocacy at The Georgetown University Medical Center. He is an internationally recognized leader in research on the human pathogen Candida albicans, the pathogenesis of invasive candidiasis, and the identification of antifungal drug targets. The research of his lab team is focused primarily on understanding gene functions related to pathogenesis, including signal transduction proteins related to cell wall synthesis, and mitochondrial energetics. Other lab research focuses on the identification of fungal-specific antifungal drug targets. Two proteins that fulfill this requirement are mitochondrial electron transport complex I (ETC1) subunits. Their fungal gene-specificity is associated with fungal-specific functions, such as cell wall mannan polysaccharide synthesis, virulence, and immunological activity.
