I am a comparative and environmental physiologist based at the University of Queensland. My research focuses primarily how the environment constrains the physiology of invertebrates, fish, amphibians and reptiles. I have a highly diverse research program that incorporates fundamental, curiosity-driven research and increasingly, a more applied research agenda in the emerging field of conservation physiology. Conservation physiology explores the responses of organisms to anthropogenic threats and attempts to determine the ecophysiological constraints dictated by current conditions and future environmental change. My research interests encompass the general areas of osmo- and ion-regulation, digestive and thermal physiology, environmental drivers of physiological function (specifically immune function and disease susceptibility) and animal performance in anthropogenically modified environments.
My lab investigates the physiological and behavioural responses of fish, frogs and reptiles to changing environmental conditions including assessing and predicting the impact of human-induced environmental change. A major thrust of this research is within the emerging field of Conservation Physiology. We are particularly interested in the capacity and plasticity of physiological systems (e.g. respiratory, cardiovascular, osmoregulatory, digestive and musculo-skeletal) to compensate and maintain performance under changing environmental conditions.
We combine lab-based experimental studies with fieldwork, and take an integrative approach that utilises ecological, behavioural, physiological and genomic methodologies. In the field we utilise remote sensing technology (acoustic and satellite telemetry, archival tags) to investigate the movement patterns and behaviours of animals in relation to environmental conditions.
Current projects include:
assessing the effects of increasing temperatures on sharks, frogs, turtles and crocodiles;
determining the physiological basis for the impact of increasing UV-B radiation on frogs;
diving behaviour and physiology of freshwater turtles and crocodiles;
acoustic and satellite tracking of sharks, turtles and crocodiles in Queensland;
regulation of physiological function in aestivating frogs
