I am an assistant professor in the department of biology at Université de Moncton in New Brunswick (Canada) since 2021. The research conducted in my lab focuses on the ecology of bryophytes and understory plants in the boreal forest, from its southern edge with the temperate forest to its northern edge. We study plant community dynamics, plant-plant, plant-soil and plant-microbiota interactions, nitrogen fixation and functional traits. I am also a contributor to the Canadian bryomonitoring initiative (https://bryomonitoring.ca/).

I grew up in Laval, a suburb of Montreal (Quebec, Canada). I have always been interested in nature and loved going out camping and hiking, a passion that came from my plant biologist and meteorologist parents. However, I initially had no interest at all in bryophytes… To me they seemed like difficult uninteresting small green things – how wrong was I! I completed my BSc in biology at Université de Montréal. My first biology job was in peatland ecology in southern Quebec. I was a bit discouraged by the challenges of Sphagnum identification and preferred focusing on vascular plants. I spent a semester at Université de la Réunion in the Indian Ocean, being amazed by the diversity of tropical areas. While I was sampling ferns with a visiting scientist, we met a team of bryologists who managed to pique my curiosity. When I came back from La Réunion, I flew directly to the subarctic to work as a field assistant in a remote field camp along the Boniface River in northern Quebec and fell in love with the North. This experience motivated me to pursue a MSc at Université Laval in Quebec City, during which I worked on vegetation-permafrost interactions. It is while working on my MSc that I (finally!) started to realize the importance of bryophytes, both in terms of biodiversity and ecosystem functions.

It is during my PhD at the University of Saskatchewan that I fell in love with bryophytes. I was investigating how climate change and changes in the fire regimes in Alaskan forests may affect bryophyte succession and ecosystem function in terms of carbon and nitrogen cycling. I was also introduced to the concept of bryosphere, i.e. the entire hidden macro- and microscopic world that lives within the bryophyte canopy. Terry McIntosh taught me the basics of bryophyte identification. The closer I looked; the more wonderful bryophytes became! I then kept working on bryophytes through my postdoctoral fellowships, studying how forest-moss-microbiome interactions shape moss-associated nitrogen fixation, an important N source in boreal forests, and using bryomonitoring to assess the spatial footprint of boreal mines with Nicole Fenton at Université du Québec en Abitibi-Témiscamingue. I still find bryophyte identification to be challenging, but it is a challenge that I now gladly undertake, and which makes me learn constantly! With the help of the late Jean Faubert and the Société Québécoise de bryologie, we even rediscovered a species of hornwort that had not been observed in Quebec for >50 years!

I am now dedicating a large portion of my research to this group of plants and share my passion for bryophytes and their beauty to as many people as possible!
