My interests revolve mostly around the ecophysiology of aquatic animals. I completed my BSc in biological and ecological sciences at the Université du Québec à Trois-Rivières, where I worked on trophic polymorphism in brook trout (Salinus fontinalis) using stable isotopes in otoliths. During my masters project at Université de Montréal I evaluated the physiological effects of parasite infection on pumpkinseed sunfish (Lepomis gibbosus). More precisely, estimating metabolism and escape response from a simulated aerial attack in sunfish across a gradient of parasite infection.
For my PhD project I’ll be working on building a bioenergetic model for Red fish (Sebastes mentella & fasciatus) using tools as respirometry (estimation of metabolism) and stable isotopes in fish’s otoliths. We wish to contribute to the very little known about Red fish ecophysiology in a goal for a better stock management of this species and the ones surrounding it.
My name is Greg. I’m a doctorate student in biological oceanography with David (our lab director). I have a formation in both theoretical and applied ecology with a master’s degree in Biodiversity, Ecology and Evolution and another one in Mathematics applied to Life Sciences. During this formation, I got the opportunity to study divers organisms among which butterflies, crocodiles and small mammals. My PhD at the ISMER focuses on the population dynamics of sebastes in the Saint-Laurent river. My goal is to use individual-based models and dynamic energy budget theory to understand the recent changes in population densities of those fish. This would help anticipate the potential impacts of these changes on the ecosystems where sebastes occur and select the right conservation actions if some come to be needed.
