Our research is focused on the metabolic and community ecology of altered environments. Human activities often create change in the form of multiple stressors, altering the community composition of aquatic ecosystems. Accurately measuring those changes is a critical first step to understanding ecosystem responses to stress. Our research group focuses on understanding how those community changes alter ecosystem energetics and function. Two broad research themes are: 1) understanding the role of multiple stressors (e.g., climate change, commercial and recreational fishing, species invasions) on the community structure and energetics of aquatic ecosystems and 2) understanding ways in which the behaviour and life histories of aquatic organisms can influence population size and ecosystem structure.
