Research Description:
Our goal is to understand how nutrient-responsive signaling pathways can be harnessed to promote health and longevity. Our recent work has focused on the role of dietary protein in regulating healthy aging; we have found that altering levels of specific dietary amino acids can improve metabolic health, reduce frailty and extend lifespan. We also investigate how rapamycin, an inhibitor of the protein kinase mTOR, regulates healthy aging in model organisms and in humans. In all of our studies, we utilize a genetics approach, using genetic mouse models to gain mechanistic insight and harnessing natural genetic variation to identify key mediators of the effects of diets and mTOR inhibitors on healthy aging and age-related diseases, including diabetes, obesity, and Alzheimer’s disease.
