About me


I’m a microbial ecologist using bioinformatics, statistics, and ecology to study host-microbe interactions on plant and in the human gut. I started my own lab at the Université de Sherbrooke in January 2020, working on plant-microbe interactions on plant host Acer saccharum (sugar maple) and Malus domestica (common apple tree) as well as continuing my work on the role of community ecology in the human gut microbiome.

During 2017-2019, I was a Postdoctoral Fellow at the University of Calgary in the Arrieta Lab working on the early-life influence of the gut microbiome on the development of the human immune system and its influence on allergies and asthma.

Take a look at the recent Q&A I did for QIAGEN.

I completed my Ph.D. (2012-2017) at the Université du Québec à Montréal, under the supervision of the mighty Steve Kembel and Christian Messier.

My interests are microbial ecology, host-microbe interactions, the human gut microbiome and its role for human health and immune system development, the phyllosphere and the rhizosphere, plant ecology, plant-microbe interactions, bioinformatics, statistics, genomics, and software carpentry.

I did my undergraduate studies in Biology at Université Laval in 2010 in Quebec City, then completed a Master in Terrestrial Ecology and Biodiversity Management at the Universitat Autonoma de Barcelona in 2011 and continued studying a Master in Statistics at Universitat Politecnica de Catalunya in 2012.

During my Ph.D. I worked on plant-microbe interactions and genomics. I used next-generation sequencing techniques to identify the members of leaf (phyllosphere) microbial communities in Quebec’s temperate forest.

Scientific happiness is only real when it’s shared. I have been very lucky to work with awesome people and this is my tribute to them.
