Dr. Dongmei Li's professional training includes 7 years of dermatology and more than 20 years of basic science research. Her clinical training is focused upon fungal infections and treatment. Since then, her research has been on fungal pathogenesis. She is currently studying mitochondria metabolic activity and its impact on candidiasis caused by the human pathogen, Candidia albicans.

In order to understand the role of mitochondrial metabolism during candidiasis, I have constructed mitochondrial mutants of the electron transport complex I subunit proteins. Mutant phenotypes are tested in vitro for changes in growth, metabolism and in vivo for virulence and reactivity with immune cells. Virulence is measured in models of disseminated infection and GI tract colonization. As the mitochondrial proteins are fungal-specific, they are exploitable as targets of new antifungals. The major areas of research thus are: 1) Mitochondrial and metabolic activities in fungal infection; 2) the role of mitochondrial and metabolic factors in host defense against invasive candidiasis; 3) mucosal site-specific immunity in candidiasis; and 4) antifungal drug target discovery.
