Field of research

Epithelial tissues of the skin, gut or lung form a barrier between the external environment and internal tissues. This exposed position makes epithelia susceptible to injury or cell transformation. My lab investigates how epithelia sense, assess and respond to these perturbations. We utilize approaches from molecular, cell and developmental biology and combine these with the excellent genetic tools and experimental tractability of the Drosophila system to explore these questions in vivo. We specifically investigate how TNF/JNK/AP-1, Cytokine/JAK/STAT and Hippo/Yki signaling pathways orchestrate cell cycle dynamics and survival at sites of tissue damage. We aim to contribute to a tissue-level understanding of wound repair and regeneration, and ultimately to a tissue-level understanding of chronic wound healing pathologies and tumorigenic transformation.
