Research

The Tatar lab combines genetics, demography, evolutionary biology and physiology of Drosophila to understand the basic mechanisms of aging. Aging is the continuous decline in somatic function that leads to progressive increase in mortality. We are particularly interested in how hormones coordinate the components of life history (growth, reproduction, and aging) by mediating nutrient allocation and components of cellular or systemic stress response. We are currently exploring how insulin-like peptides respond to nutrition and thereby mediate secondary endocrines such as neuropeptides, juvenile hormone, and ecdysone, and then how these hormones affect reproduction and aging. Many stress response systems are of interest to our lab, including heat shock proteins, cellular anti-oxidant enzymes, and innate immunity.
