Tissue morphogenesis, repair and regeneration requires cells to communicate and coordinate their behaviours. Major pathways involved are the Wnt/Frizzled and Fat/Dachsous planar polarity pathways that mediate polarised cell signalling in epithelia sheets. Loss of their activity leads to a variety of developmental abnormalities in animal models such as failure of neural tube closure, cleft palates and heart defects, as well as deficits in wound healing and failure to repair kidney damage resulting in polycystic tubules, and is also implicated in cancer metastasis.

The project will focus on understanding molecular mechanisms of Wnt/Frizzled and Fat/Dachsous pathway activity, and in particular how individual proteins adopt polarised distributions with cells, and the signalling mechanisms that propagate this polarity from cell to cell. A molecular genetic approach will be used, taking advantage of the well-established model Drosophila, which provides sophisticated molecular and genetic and cell biological tools. A major focus in the lab is understanding protein dynamics during cell signalling, using techniques such as live imaging (both conventional and super-resolution) and FRAP, and combining this with genetic screens to identify new pathway components and cell biology and biochemical studies of protein behaviours. We combine these experimental studies with computation modelling approaches to aid in experimental design and hypothesis testing.
