    behavioural ecology, evolutionary physiology, animal physiology, freshwater and marine fish, birds, telemetry, physiological sampling techniques


    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.

    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.

    Graduate Students

    We’re looking for Graduate students for these projects:

    1. Physiological costs of reproduction and carryover effects in Common Eiders breeding in the Canadian Arctic (PhD, 2013-2016).

    2. Physiology, overwinter behaviour, and survival in sympatric Atlantic salmon and Arctic Char populations in Labrador and Newfoundland (PhD, 2014-17).

    3. White sturgeon bioprobe project: examining the reproductive biology and movement ecology of a cryptic species in the Fraser River, British Columbia (PhD, 2014-2017).

    4. Migration studies of Atlantic salmon in Nova Scotia rivers and lakes (MSc, 2013-2014).

    If you are interested in the research that my lab undertakes, or have ideas of your own that are related to our research, please send me a copy of your CV and a letter describing your interests. Our aim is to nurture your research interests and to provide all the support needed to achieve your goals. And as part of a large research group, there is ample opportunity to learn new skills and to interact and collaborate with other enthusiastic scientists.

    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.
