I am interested in a variety of questions of stem cell biology: How do stem cells maintain their identity throughout development and how do they decide whether to divide or whether to become quiescent? How is growth regulated in stem cells and what are the signals controlling this? How do adult stem cells age over time and become competent to initiate tumours? The biological systems we are using to unravel mechanisms underlying these questions are the embryonic/larval neural stem cells, neuroblasts, and the adult intestinal stem cell of the fruit fly Drosophila melanogaster.
Key techniques: Immunohistochemistry, RNAseq, qPCR etc.
Research system/organism: Drosophila melanogaster
