The Quinn Group's current research involves generating genetic models using the vinegar fly (Drosophila melanogaster) to understand the initiation and progression of human cancer. Her core research uses in vivo cancer models to determine how complex developmental signalling pathways are integrated into transcriptional networks. In particular, we aim to understand how these networks coordinate cell growth and division to establish the body plan during development and also maintain tissue homeostasis in adult animals; as cell growth and proliferation are invariably dysregulated in human cancer. Her group also has a strong interest in using in vivo stem cell models to determine the mechanism(s) by which the stem cell microenvironment or “niche” regulates stem and progenitor cell growth, division and differentiation.
Enquiries are welcome from potential Honours or PhD students. A variety of projects are available within all of the areas of research undertaken by this Group. Please contact us.
