My research focuses on using C. albicans as a model fungal pathogen. C. albicans is a frequently acquired nosocomial infection both within the US and worldwide. It is an increasingly common threat to human health as a consequence of AIDS, steroid therapy, organ and tissue transplantation, cancer therapy, broad spectrum antibiotics and other immune defects. These infections carry unacceptably high morbidity, mortality rates (30-50%) and important economic repercussions (estimated total direct cost of approximately 2 billion dollars in 1998 in US hospitals alone).
The objectives of my research are: (i) the application of state-of-the-art yeast cell biology and genetics to the study of Candida albicans pathogenesis and commensalism, (ii) the use of proteomics, genomics, and bioinformatics in the analysis of the lifecycle of C. albicans, (iii) studies of C. albicans virulence in vivo, and (iv) signal sensing and transduction particularly with reference to disease related and quorum sensing pathways in C. albicans.
