Senior Research Scientist within the Healthy and Resilient GBR Program where I lead frontier research into the roles of microbial and viral 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
My research assesses the impact of environmental pressures on reef bacterial symbiosis. This research primarily focuses on sponges and quantifies the stress response on all symbiotic partners of each life history stage using a variety of molecular techniques. In 2012 I was awarded an ARC Future Fellowship for a project entitled Revealing the structure, evolution and sensitivity of symbioses in basal metazoa. This research will explore the functional roles of bacteria, archaea and viruses within the sponge holobiont and assess whether they can enhance the acclimatization and adaptive capacity of the sponge during a rapidly changing climate.
