Research Interests

One focus of my research is in utilizing the model eukaryote Saccharyomyces cerevisiae to further our understanding of fundamental metabolic pathways. Environmental and cellular stresses have profound effects on gene regulation in eukaryotic organisms, ranging from complex mammals such as humans to the simplest organisms such as yeast. Saccharomyces cerevisiae is an ideal microorganism used to investigate gene regulation, both in mapping regulatory networks and resolving the dynamics of signal transduction pathways.  My research has largely focused on three areas of nutrient utilization: the Retrograde system, NCR (nitrogen catobolite repression)-sensitive gene expression, and carbon metabolism.
