About
Introduction
I currently work at Marine Science Institute (ISMER, Rimouski, QC), doing research in biological Oceanography. More precisely, I work on a so-called glacial relict Mysid population (Boreomysis nobilis Sars 1879) in Saguenay Fjord, QC. The aim of my project is to define wether or not the Saguenay population is a relict, and if their metabolism evolved facing more warm and changing thermal regime of Saguenay Fjord. Under supervision of Dr. Gesche Winkler (ISMER) and Dr. Piero Calosi (UQAR), I sampled the third basin of the fjord last July, looking for the rare specie B. nobilis. A total of 107 individuals were sampled. Next step will be to sample in the Arctic Ocean, which is planned on taking place in summer 2019.

Projects
Project (1)
In this project we aim to know if B. nobilis is a glacial relict from last Glacial Maximum. We also want to know if it adapted somehow to the warmer and more variable thermal regime of Saguenay fjord when compared to the bulk of the specie, living in the Arctic Ocean. We want to test enzymatic performances at different temperature reflecting both Arctic and Saguenay regime. This way, we aim to underline any differential performance, which could then be linked to alleles specific to a region, for example. Field sampling already took place in July 2018 in Saguenay fjord. Lab work should start during 2019 winter, as Arctic expedition could take place in summer 2019.
