I obtained a PhD in 2001 which investigated the microbial ecology of a GBR sponge, focussing on the stability of the symbiotic associations over different latitudinal and stress gradients. Between 2001-05 I undertook postdoctoral research at the University of Canterbury / Gateway Antarctica. This research investigated the utility of microbial symbionts as biomarkers for environmental stress in the Antarctic marine ecosystem and facilitated the development of effective diagnostic tools for measuring sub-lethal stress in Antarctic marine biota. In 2005 I commenced a research scientist position at AIMS undertaking research that assesses the impact of environmental stress on model invertebrate symbioses (primarily sponges and their microbial symbionts). During this period I also undertook research into the role of microorganisms as inducers for settlement and metamorphosis of coral reef invertebrates.
