Research

I am generally interested in aquatic research that has a conservation focus. I have a varied background with academics, private consulting, and government providing me with lots of fisheries and aquatic experience. During my MSc, my research was on ways to mitigate freshwater turtle bycatch in a fyke net fishery in Ontario using aspects of fisheries catches and physiology. I have extensive experience with fish and fish habitat quantification and knowledge of legislation working as a fisheries biologist for consulting companies. I have also worked for and/or collaborated with both the federal and provincial government in terms of fisheries management and fish and fish habitat research. I draw upon my extensive

background and experiences to be multi-disciplinary, in which I am now pursuing my interests in movement and predator-prey interactions by using a combination of telemetry and stable isotope analysis to infer spatial and trophic niches and their dynamics.

 

My Ph.D. research focuses on the interactions of salmonid fish species for spatial and trophic niches and the influence on restoration efforts of the extirpated Atlantic Salmon (Salmo salar) in Lake Ontario. Specifically, I will be looking at these interactions at both the juvenile and adult life stages

in the river and lake environments, respectively. This research will provide insight on how seemingly similar niche species co-habit and partition the environment and resources. With respect to species restoration, I will discern whether niche overlap in a system of introduced and stocked non-native salmonids in Lake Ontario is preventing species such as the Atlantic Salmon from obtaining self-sustaining populations.
