Research Interests

Research in my laboratory is currently focused on understanding the interaction between NAD+ homeostasis and calorie restriction (CR)-related nutrient sensing pathways, and their regulation in budding yeast Saccharomyces cerevisiae. The main goal of our research is to utilize the genetically tractable yeast S. cerevisiae to identify factors that regulate NAD+ homeostasis and longevity pathways. Understanding the mechanisms of these molecular processes in yeast may provide clues to the molecular basis of human aging and age-associated diseases.
