My primary research interest concerns the ecological physiology of marine animals, mainly gastropods. I have had a long interest in the metabolic regulation of gastropods. My research also considers the responses of tropical intertidal animals to climate change. Studies involve assessing performance and tolerance of organisms to temperature variation and exposure to acidified seawater. A current focus is on understanding the susceptibility of gastropod shells to dissolution, shell compensatory processes and using gastropod shells to biomonitor levels of marine acidification. Other research concerns quantitative ecology of marine estuarine systems and tropical marine diversity.


Marine organismal responses to global change - warming

This project will consider how intertidal ectotherms behaviourally thermoregulate and acclimate to the temperature extremes experienced when exposed in air. We are especially interested in unraveling the nature and mechanisms of rapid heat hardening. Other elements include multi-stressor responses, such as the coupled effects of heating and drying when air-exposed.

Applications Invited
PhD, MSc

Metabolism and energetics associated with snails living under extreme and variable pH circumstances

This project will explore the constraints on energetic balance of circumstances leading to limited energetic uptake and the apparently high energy costs of life in acidified estuarine ecosystem. It will involve gastropods as a model system.
