Stem cells maintain the function of many of organs and are also highly influenced by metabolism and physiology. My lab focuses on identifying the metabolic and physiological mechanisms that link the behavior of stem cells and their descendants to diet, stress, and other systemic inputs. To investigate these broadly relevant questions, we take advantage of a powerful genetic model organism, the fruit fly. Fruit flies have well characterized and readily identifiable stem cells, fascinating and complex physiology, and highly evolutionarily conserved biological processes. Our research generates fundamental knowledge about the integration between metabolism and physiology in the control of stem cell lineages in vivo, with potential insights into how deregulation of these processes is tied to stem cell-related diseases.
