Biography

I obtained a master’s and a doctorate’s degree in the laboratory of Dr. Yves Bourbonnais at Université Laval and I am now specialized with the use of the yeast Saccharomyces cerevisiae as a working tool and as a model organism. Being easy to manipulate genetically, this single-celled organism allows us to try to answer many scientific questions of interest for the laboratory. My work in the laboratory of Dr. Christian Landry can be divided into three parts (administration, instrumentation and experimentation) which are making me a resource person (commonly named “the mom of the lab”) for students and researchers.
