Associate Professor

Research | Current

My research interests are varied and include sensory physiology of fish (including sharks) and crustaceans, vocal communication in fish, recruitment processes in fish and crustaceans and the biological role of underwater sound.

I am particularly interested in the sensory physiology in fish which has been the basis of two productive international collaborators Professor Dennis Higgs (University of Windsor, Canada) and Professor Allen Mensinger (Marine Biological Laboratory, USA). My other interest is in the biological role of ambient underwater sound and in particularly the role of soundscape ecology in the marine environment.

Some examples of current projects are; the role the lateral line plays in fish sound source localisation, vocalising behaviour of the New Zealand Bigeye, using passive acoustics as a environmental monitoring tool, and the role of acoustics in the competitive patch foraging between large pelagic predators.
