Self-introduction
Using yeast S. cerevisiae and nematode C. elegans, I study the functions regulated by nutrient signaling, such as cell growth, metabolism, and stress resistance, as well as the mechanisms by which nutrient responsiveness declines with aging, aiming to gain insights into the significance of nutrient sensing mechanism in the process of aging.
