Introduction
I'm interested in fish ecology, fish movement and behaviour, trophic dynamics and bioenergetics. Currently, I am studying the effects of habitat fragmentation on lake trout and black bass populations in a multibasin lake system. In addition, I'm interested in the impacts that environmental and/or anthropogenic stressors (e.g. climate change) have on fish and fish populations.

Position
- Laboratory Assistant
Description
- Analysed steroid levels using enzyme immune assays (EIAs) on fish gonads collected from rivers near the Canadian oil sands. Analyzed data from EIAs and evaluated statistical differences using R programming.

Invasive sea lamprey (Petromyzon marinus) populations in the Great Lakes are controlled by applying the piscicide, 3-trifluoromethyl-4-nitrophenol (TFM), to infested streams with larval sea lamprey (ammocoetes). While treatment mortality is > 90%, surviving lamprey, called residuals, can undermine control efforts. A key determinant of TFM effective...
Recreational catch-and-release angling (C&R) is prevalent and growing in popularity, along with concerns over the welfare of released fish. Although there have been many studies quantifying post-release mortality in fish exposed to C&R, there is growing interest in understanding and minimizing any sublethal consequences of recreational fisheries in...
The sensitivity of larval sea lamprey (Petromyzon marinus) to the lampricide 3-trifluoromethyl-4-nitrophenol (TFM) varies with season, with highest sensitivity in spring and tolerance increasing by 2- to 3-fold in the mid-late summer. Until recently, the physiological basis for these differences was unresolved. Using previously published and unpubl...
Winter is a challenging period for aquatic research—weather is uncomfortable, ice is hazardous, equipment fails, and daylength is short. Consequently, until recently relatively little research on freshwater fishes has included winter. Telemetry methods for tracking fish and observing movement behavior are an obvious solution to working in harsh con...
Invasive sea lampreys (Petromyzon marinus) in the Great Lakes are controlled by applying the pesticide (lampricide) 3-trifluoromethyl-4-nitrophenol (TFM) to waters infested with larval lamprey. However, treatment effectiveness can be undermined by “residual” larval sea lamprey that survive TFM exposure, and subsequently complete metamorphosis into...
Effects of pH on the speciation of 3-trifluoromethyl-4-nitrophenol (TFM) and uptake rates of larval sea lamprey when exposed to 4.2 mg TFM L −1. Changes in uptake rates of 3-trifluoromethyl-4-nitrophenol (TFM) by larval sea lamprey and the speciation of TFM at different pHs (low, moderate, and high pH) when exposed to 4.2 mg TFM L −1. The interacti...
Effects of pH on the speciation of 3-trifluoromethyl-4-nitrophenol (TFM) and uptake rates of larval sea lamprey when exposed to 7.0 mg TFM L −1. Changes in uptake rates of 3-trifluoromethyl-4-nitrophenol (TFM) by larval sea lamprey and the speciation of TFM at different pHs (low, moderate, and high pH) when exposed to 7.0 mg TFM L −1. The interacti...
Spermiating male sea lamprey (Petromyzon marinus) release a sex pheromone, of which a component, 7α, 12α, 24-trihydoxy-3-one-5α-cholan-24-sulfate (3kPZS), has been identified and shown to induce long distance preference responses in ovulated females. However, other pheromone components exist, and when 3kPZS alone was used to control invasive sea la...
Invasive sea lampreys continue to plague Great Lakes fisheries. To control this nuisance species, streams containing larval sea lampreys are treated with the pesticide 3-trifluoromethyl-4-nitrophenol (TFM) every 2-4 years. However, TFM application takes place from spring to fall, suggesting that variation in the sensitivity of larval lampreys to TF...
