Internal organs are constantly exchanging signals, and can undergo profound anatomical and functional changes in response to them, even in fully developed organisms. Such organ plasticity results from a need to integrate and respond to both environmental information and internal state, and is key to maintaining homeostasis and driving adaptive changes. We are interested in understanding the mechanisms by which organs sense change and respond to it: the molecules, cellular events and physiological adaptations involved. The intestine and its neurons are a fantastic system with which to tackle these questions. Our main model system is Drosophila melanogaster, but we are beginning to explore the evolutionary conservation of some of our findings in mice and humans through local and international collaborations.
II received a D.Phil. in Genetics from the University of Oxford, UK, where I developed invertebrate models of human disease with Prof. Dame Kay E. Davies. My postdoctoral work with Prof. Stefan Thor, first at Harvard, USA and then Linkoping University, Sweden, identified the first genetically defined enteric neurons in Drosophila. I was awarded a Marie Curie Fellowship to undertake further postdoctoral work with Prof. Alex Gould at NIMR, London, where I uncovered similarities between the specification of gut-innervating insulin-producing neurons in flies and pancreatic beta cells in mammals. In 2008, I obtained an independent Wellcome Trust Research Career Development Fellowship to capitalize on the study of the enteric nervous system in Drosophila, first at the University of Cambridge and now in London. I was elected to the EMBO YIP programme in 2012 and am the recipient of an ERC Starting Grant.
