- Understanding the basic biology of aging by using targeted interventions to delay the aging process in mammals. A focus on the lab is understanding how the inhibition of the mTOR signaling pathway can be used to delay aging and improve health. We use both rodents and non-human primates as model systems to address these questions. Some key questions we address are 1) does mTOR inhibition have similar effects in both model systems, 2) can diet interact with the pro-longevity effects of mTOR inhibition, 3) could multi-drug treatments be used to promote longevity and reduce potential side-effects.
- Determining whether modulation of oxidative stress could regulate healthy lifespan; i.e., does reduction of oxidative stress slow the development of age-related disease? In particular, we are interested in studying the role of oxidative stress and protein oxidation in the development of metabolic dysfunction with age and obesity. The oxidative stress theory of aging has been one of the most prominent theories of why organisms age. Both aging and increased fat accumulation promote dysregulation of glucose metabolism, alterations in adipose tissue homeostasis, and declines in cellular function that are detrimental to overall health. Metabolic diseases like Type 2 diabetes currently affect a significant proportion of the world's population and their prevention could certainly lead to longer, healthier lives.
