My research focuses on investigating regulatory mechanisms of eukaryotic gene expression.  Currently, my laboratory is focusing on genes that are involved in fungal cell wall metabolism.  The fungal cell wall, which is composed of polysaccharides and glycoproteins, is essential for growth and metabolism of the fungus and is an excellent target for antifungal drugs.  We have identified several genes that play specific roles in cell wall metabolism in the filamentous fungus Aspergillus nidulans including genes that have homologues that have been found to be involved in establishing and maintaining cell wall integrity in yeasts and several other previously uncharacterized genes.  Experiments are being conducted to investigate the regulation of message production of these genes, to observe the cellular localization of the proteins during different stages of fungal development, and to learn more about the specific role of each of them in cell wall metabolism.
