I work across broad disciplines in aquatic biology, marine ecology, aquaculture and fisheries, biochemistry, immunology, molecular biology, and ecotoxicology. Particular research foci include characterisation of molecular mechanisms involved during embryonic and larval development of marine invertebrates, and in response to environmental influences e.g. ocean acidification, pollution, pathogens. Gaining a better understanding of biochemical regulatory networks involved during early development and in response to environmental change is critical for the successful management of our oceans and the organisms which inhabit them. Other research interests include characterising mechanisms of disease and resistance in marine organisms, development of new tools for assessing fish/shellfish health, and protecting, restoring and promoting sustainable use of marine ecosystems.
