All organisms regulate their growth according to internal genetic programmes and the availability of nutrients from the environment. As human and other animal embryos develop, they increase in size dramatically. We wish to identify the nutritional factors and genetic networks that promote growth during development and, equally importantly, those that shut it down in adulthood. This research also aims to shed light on the complex interactions between nutrition and the genes influencing growth, obesity and diabetes.

Our current work aims to understand how embryonic and fetal growth are altered by sub-optimal nutrition. Much of our research in this area uses the fruit fly Drosophila, a model organism that shares many genes with mammals. We recently found that restricting nutrient intake during Drosophila development reduces growth in certain organs, such as the brain, to a much lesser extent than in others. We have now identified several conserved genes regulating this selective brain sparing process and are currently examining whether they play a similar role in mammals.
