Dr. Richard Calderone is Professor & Chairman of the Department of Microbiology & Immunology. Director of the M.S. program in Biomedical Science Policy & Advocacy.
- Ph.D., West Virginia University, 1970
- At Georgetown Since: 1974

The focus of research in the Calderone laboratory is on the two most common fungal pathogens of immunocompromised patients, Candida albicans and Aspergillus fumigatus. We use molecular biological and biochemical approaches to identify new targets on these fungi that can be exploited in drug discovery. In this regard, the potential drug targets that have been identified are two-component signal transduction proteins. In addition, in C. albicans, we study DNA repair and again focus upon identifying unique proteins that may have potential as drug targets. Our collaboration with a medicinal chemist has resulted in 4 compounds in patent that we hope to further develop. The lab is supported by NIH funds and the research staff in the lab currently includes 2 PhD students and 2 research Assistant Professors and a post-doctoral fellow. (Has both potential capacity for new doctoral students and/or research staff.)
