Research Summary
Living organisms can cope with disruption of homeostasis such as injury and disease to a certain degree. This results in restoration of steady state homeostasis, death of affected tissues or ultimate organismal death. The outcome depends on the type of insults, species of animals and maturation of tissues. While the process is well recognized, we still do not know the mechanisms defining responses to disruption of homeostasis in different organs and species. Our research focuses on three fundamental questions targeting major disruption of homeostasis in organisms: 1) How do animals repair tissues upon injury? 2) How does oncogenic stress by cancer affect animals? 3) What is the mechanism of aging? To do this, we utilize unrivaled genetics of the fruit fly, Drosophila melanogaster.
