The focus of the Systems Biology of Aging Laboratory is to use genetic, genomic, proteomic, and metabolomic approaches to investigate how organs communicate with each other through secretion of hormones to regulate whole-body homeostasis, and how this process gets dysregulated in aging. The age-associated organ function decline involves multiple cell intrinsic events. Most physiological processes however are orchestrated by cell extrinsic events, therefore aging is also a consequence of progressive breakdown of extracellular environment. This milieu is constituted of endogenous metabolites, hormones, and nutrients, which proffers potential targets for increasing healthy longevity. We aim to identify extracellular milieu factor(s) that change with age to identify novel avenue to treat diseases of aging. 

We have extensive expertise in bone, skeletal muscle, adipose tissue, pancreas, liver, reproductive, gastrointestinal tract and brain structure and function analysis. We welcome collaboration requests from other laboratories to extend our expertise in various organ physiologies to contribute towards understanding the biology of aging. Together we can identify molecular targets, nutritional cues, and lifestyle changes to increase healthy lifespan in humans.
