My research focuses on functional genomics in budding yeast and the human fungal pathogen Candida glabrata. We are focusing on the Gal4 family of transcriptional regulators. The function of many of these Gal4 members is unknown or poorly defined. To better understand the role of these transcriptional regulators and identify their target genes, we are using various approaches including genetics, molecular biology and whole-genome analysis of gene expression with DNA microarrays. We are also determining the role of related Gal4 members in conferring resistance to antifungal drugs in the human pathogen Candida glabrata.
