Research interests

I am an environmental scientist with over 25 years experience in the field of ecotoxicology and environmental risk assessment. I studied at the University of Sydney (NSW, Australia) where I obtained both my Bachelor of Science (Honours, 1992) and my Doctor of Philosophy (1999) degrees. My research projects for both degrees focused on ecotoxicology in marine environments. For my doctoral thesis I investigated the impact of metals and organic contaminants on sensitive early life history stages of marine invertebrates. My doctoral work was a collaboration with the Aquatic Toxicology group, Sydney Water, with whom I worked as an Environmental Scientist during this period. After graduating, I completed a Post-Doctoral Research Fellowship at the Centre for Environmental Contaminants Research at CSIRO in NSW. During my Post-Doc, I conducted research on the bioavailability, bioaccumulation and toxicity of contaminants in waters and sediments to benthic marine invertebrates, and contributed to the development of the Handbook for Sediment Quality Assessment for Australia.

My first experience working in Antarctica was during my doctoral degree. I was fortunate to be invited to join a research project within the Human Impacts Research Program, and spent the 1996–97 and 1997–98 summers conducting research on the impact of a rubbish tip and wastewater discharge on near-shore sediments and biota. This involved both field-based biomonitoring and benthic community surveys, and laboratory-based bioaccumulation studies and toxicity tests.

In 2005 I began working as a Research Scientist at the Australian Antarctic Division, where I have continued to develop a portfolio of ecotoxicology research on Antarctic and subantarctic species. Most of my research during this period has focused on determining the sensitivity of a range of species to common contaminants that occur in the Antarctic environment, especially metals, fuels and complex wastewater mixtures. I am particularly interested in factors that control contaminant bioavailability and that affect the sensitivity of organisms to contaminants, and the sensitivity and vulnerability of organisms to stressors associated with environmental change. The research I do encompasses both marine and terrestrial environments, with the ultimate aim of developing site-specific environmental quality guidelines for Antarctica and subantarctic regions. I have led and contributed as a co-investigator to over 20 Antarctic-based research projects, over the course of which I have supervised nearly 30 postgraduate research students. I am currently positioned as a Senior Research Scientist, leading the Ecotoxicology Research group within the Antarctic Conservation and Management Program at the AAD.

My current research portfolio requires that I manage a suite of diverse multidisciplinary teams that deliver strategically important robust scientific research that contributes to evidenced-based decision making in policy and operational developments both for the Australian Antarctic program, and internationally through the Committee for Environmental Protection (CEP).
