I was born and raised in Montréal, where I so far spent the better part of my life. With the specific goal to pursue a career in scientific research, I did my undergraduate studies in biochemistry at Université de Montréal, where I enjoyed my first research opportunities. I then moved to McGill University for a master’s degree in microbiology, doing crystallography with bacterial membrane proteins. After an internship in the Department of Physiology at UCLA, I joined the laboratory of Pr. Vincent Martin at Concordia University for a Ph.D. in biology, where I applied metagenomics and genome editing methods studying the determinants of selection in evolutionary engineering experiments with yeast. After this challenging and rewarding experience, during which I discovered the fascinating field of evolutionary biology, I joined the corporate R&D labs at Lallemand Inc, a company specialized in the development, production and distribution of yeast and bacteria products. In this role, I continued nourishing my interests in evolution, working on several evolutionary engineering projects with various microbes. To further pursue these interests, I joined the Landry lab in February 2019.


Research interests

My broader interest is in understanding how environmental conditions and population structure constrain the trajectory of microbial evolution. Specifically, I am interested in evolutionary responses, in particular compensatory evolution, to the fitness cost of beneficial alleles. Therefore, I have a keen interest in epistasis, and antagonistic pleiotropy. I thrive designing and executing evolution experiments, and thoroughly enjoy genomics and computational biology work.
