My research interests are focused in the field of crustacean ecophysiology, in particular how animals use respiratory and cardiovascular mechanisms when adapting to environmental change. Recently we have been investigating digestive processes in crustaceans and how animals modulate mechanical digestion, enzyme activity and protein synthesis. Many of these findings are applicable to fisheries or aquaculture. I am also interested in crustacean behaviour; how various behaviours often have a physiological basis and help adapt the animal to changes in environmental conditions. We use both lab and field based (telemetry and CTD data tags) approaches to answer these questions.
