Research interests

  • Forest vulnerability to climate change
  • Phenology of wood formation
  • Biotic and abiotic drivers of drought sensitivity


Loïc joined the faculty in 2018. He holds a BSc and a MSc in Biology from the Université de Montréal, with a PhD in Renewable Resource Sciences from McGill University. Prior to moving to New Brunswick, Loïc completed postdoctoral internships at Indiana University (USA) and Université du Québec à Montréal, and was a visiting scholar at Harvard Forest in 2017-2018.

Loïc has been involved in several climate change experiments in Eastern Canada, in controlled environments as well as in boreal stands, to detect ecosystem vulnerability to global warming and associated increases in drought. In complement, he has designed large-scale studies that use inventory-based tree-ring collections to detect climatic thresholds in the growth dominant tree species.
