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 fundamental questions targeting major disruption of homeostasis in organisms:
How does oncogenic stress by cancer affect animals?
What is the mechanism of aging?
How do animals cope with malnutrition?
Why are tissue stem cells perseverant?
How do cell death and stem cell proliferation coordinate?
To do this, we mainly utilize unrivaled genetics of the fruit fly, Drosophila melanogaster.
