Research

I am a plant physiologist studying functional phenology and the effects of plant-environment interactions on metabolic regulation, carbon sequestration and photosynthesis in trees. My research is centered on the question, how boreal forests will respond to a future warmer and drier climate? Current projects aim at understanding the effect of future warmer and drier climate on the regulation of phenological events, productivity and survival of conifer trees. This is studied from cell to canopy level using controlled mesocosms (growth chambers), manipulative field experiments, and through collaborative work at multipartner monitoring sites. My lab integrates genomic, physiological and biochemical approaches to understand the mechanisms by which plants sense, and respond to the environment.
