Local and systemic functions of the adult intestine in health and disease

Research in my laboratory is devoted to understanding how intestinal stem cells (ISCs) adapt and respond to changes in their micro and macro-environment, how the intestine senses and controls whole-body homeostasis and how intestinal dysfunction can lead to broader organismal instability. We use the fruit fly Drosophila melanogaster as a primary research model system due to its unparalleled genetic power and amenability for multi-organ in vivo studies combined with experiments in mammalian systems.
