Biology
I've been a PhD student in Biology at Université Laval for the past 4 and a half years. Before that, I did my bachelor's degree at the Université de Liège, in Belgium, then my master's in Quebec under the supervision of Nadia Aubin-Horth. I'm passionate about sport. My research interests are to improve our knowledge of the processes by which living beings adapt to new environments. At the moment, I'm particularly interested in the genetic changes that enable adaptation in a species of fish called the threespine stickleback.
Project: Mapping adaptation: population structure of the threespine stickleback from the Saguenay to the St. Lawrence
"Can we really adapt to everything? That's the question posed by the three-spined stickleback, a small fish found in both the salt waters of the estuary and freshwater streams. How does it manage to survive in such contrasting environments, when salinity can turn an organism upside down?
The answer lies in its genome. Each stickleback population has genetic particularities that reflect its history and environment. Some are discrete - single-letter changes in the DNA (SNPs).
In this project, you'll use these genetic markers to study stickleback population structure in a unique environment: the Saguenay Fjord. Using bioinformatics tools and real data, you'll delve into the heart of current research in evolutionary biology, to better understand how populations differentiate, disperse... and adapt.
