Research Interests

Changes in protein expression underlie cell activity. One way to control protein levels is through post-transcriptional regulation of mRNAs, which can be localised to sub-cellular domains. This conserved mechanism for the spatial regulation of gene expression enables cells to target protein function in space and time and is especially relevant in the patterning of embryonic axes, formation of neuronal networks and movement of cells. Failure to control localised translation is implicated in a number of human diseases, including Fragile X Syndrome, schizophrenia, spinal muscular atrophy and cancer.

Localised translation is especially crucial at times when cells transition from one fate or function to another. Egg activation in many animals is one such transition and in part involves a wave of increased intracellular calcium, reorganisation of the cytoskeleton and release from cell cycle arrest. 

To understand how the fundamental processes of localised translation and egg activation are achieved, we use Drosophila as a model system since imaging, biochemistry and genetic approaches can be readily combined to examine molecular mechanisms. Drosophila research has identified thousands of genes with human homologues and has provided key insights into developmental pathways, oncology, neurobiology and immunology. Our use of the egg chamber and early embryo has the added experimental benefits of: being an in vivo developing system; allowing for a controllable switch at egg activation; ease of physical manipulation; and providing ample material for experimentation.
