Research interests

  • Forest vulnerability to climate change
  • Tree ecophysiology
  • Tree growth and stand productivity


Loïc joined the faculty in 2018. He holds a MSc in Biology from the Université de Montréal, and 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.

His research program leverages different approaches to tackle the vast question of forest response to climate change. Climate change experiments (in situ or under controlled environments), high-precision monitoring of tree ecophysiology (radial growth, transpiration, respiration) and large-scale analyses of tree growth data collections are all used to assess climatic thresholds in the growth and health of Acadian tree species.
