I believe science has a central role in helping us address the immense challenges facing the planet in the future. In this regard I am interested in understanding the resilience of marine animals to biotic and abiotic perturbations at the population, individual and molecular level. I am particularly interested in what metabolic strategies animals employ to maintain homeostasis within a fluctuating environment and how we might use this information to predict the effects of future climate change, and where relevant sustainably manage economically important species. The model organisms I use are broad and encompass seabirds, fish and intertidal invertebrates.

Potential projects could include (but happy to discuss ideas)

Diving and stress physiology of seabirds

Predicting climate change effects via mapping thermotolerance of intertidal/coastal invertebrates

Improving aquaculture sustainability via mapping physiological responses of invertebrates in aquaculture systems

Characterising population connectivity of coastal invertebrates via LA-ICP-MS tracking of larval dispersal
