Sir John Walsh Research Institute researcher profile

Dr Kyoko Niimi

PositionHonorary Senior Research Fellow
DepartmentDepartment of Oral Sciences
QualificationsDVM (Kyushu Dental) PhD (Otago)
Research summaryMolecular mycology, antifungal resistance, drug discovery

Research

Dr Niimi's research interests are in molecular microbiology, particularly in mycology research and the development of drug efflux pump inhibitors. Her three main areas of research expertise are the molecular biology of human fungal pathogens Candida albicans and Candida glabrata, the mechanisms of antifungal drug resistance, and heterologous protein expression in baker's yeast Saccharomyces cerevisiae.
