My research examines human impacts on the evolution of coral reef fishes. The ultimate goal is to characterise and mitigate threats to marine biodiversity and fisheries resources.

This research covers a range of scales from global studies on macroecology, phylogeography and biogeography through to long-term monitoring of population changes and studies of life history traits, behaviour, sensory systems and stress responses of individuals. To conduct this research requires a combination of fieldwork, aquarium experiments, and laboratory analyses. Although this research spans a range of organisms, the main study group is anemonefishes (clownfishes).
