Originally from Sherbrooke, I completed my bachelor’s degree in microbiology at Sherbrooke University. At that time, my main research interests surrounded developmental biology. Moving forward, I diverged towards neuroscience during my master's degree in physiology, in which I studied the relationship between attention, impulsivity, and white matter microstructure in school-aged children. I am pursuing doctoral studies in physiology at Sherbrooke University, investigating the link between cognition, behavior, and cerebral neurophysiology. Aside from academics, I am a Formula 1 super fan 🏎️, a long-time hockey player 🏒, and a part-time golf player ⛳!
