It has long been known that restricting nutrient/calorie intake promotes health and extends lifespan. However, the consequences of reduced nutrient uptake are not understood at the most basic level of our biology -- our genes. Understanding how our genes respond to nutrients is essential in order to design therapies/dietary strategies and to identify naturally occurring molecules found in foods to combat age-related disease and increase lifespan. The work in my laboratory aims to identify not only the genes involved in mediating health and longevity but also the mechanisms that drive this. Furthermore, my goal is to understand how nutrient availability and sensing impact genome folding, influencing in gene expression, leading to increased health and longevity.
