Principal Research Scientist within the Healthy and Resilient GBR Program where I lead research into the roles of microbial symbionts in invertebrate health and adaptation to changed environments.
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.

Current Research Activities
The health of reef ecosystems is underpinned by a diverse array of microorganisms that undertake essential biogeochemical transformations and which live in intimate symbioses with reef hosts. My research explores the various ways in which microorganisms contribute to reef health. We undertake experimental and field based research and use sensitive molecular approaches to define host and microbial sensitivity thresholds to different environmental pressures. Our research also explores how microorganisms can contribute to the transgenerational acclimatisation of reef invertebrates in a rapidly changing climate.
