y lab has interests in all aspects of animal physiology, behaviour, and ecology. Research efforts are focussed primarily, though not exclusively, on freshwater and marine fish species, and on birds. Telemetry and physiological sampling techniques are major tools in our research.

Sampling macaroni penguins at a large breeding colony at Bird Island, South Georgia

Specific interests include the physiological and evolutionary responses of animals to natural and anthropogenic stressors. By coupling telemetry and physiological sampling techniques, I examine how individual variation in physiological condition affects migratory performance and future reproductive investment and organismal fitness.

Whenever possible, I also seek to apply these findings to issues concerning the conservation of aquatic and avian resources, with the aim of understanding, and hopefully predicting, the response of populations to environmental change.

Undergraduate Honours Positions:

I anticipate having one or two positions available each year for Undergraduate Honours Thesis students (e.g. BIOL 4900). Ideally, thesis projects would involve some field work and data collection, but may more typically involve laboratory and/or data analyses. Ultimately, most projects will have a focus on the physiological underpinning of life-history variation, in either fish or birds, and will usually involve telemetry and behavioural data. Honours projects are a great introduction to research, to what life would be like in graduate school, and to what science is like as a career.
