My research focuses on quantitative ecology and ecophysiology, and in particular on modelling the complex responses of plants to multiple environmental factors and predicting the phenological adaptation of trees to climate changes. Investigations include long-lasting observations in permanent plots across wide geographical ranges, manipulated experiments in nature, assisted migration of ecotypes, and experimental designs under strictly-controlled environments. My actual projects are related to the dynamics of tree growth and reproduction at local to global scale and how the effects of climate change on forest productivity can be taken into account by the new strategies of forest management. I am considered a pioneer of the studies on wood formation in temperate and cold ecosystems and treeline ecotones. I have successfully realized several meta-analyses on the recurrent timings of tree growth across the Northern hemisphere.
Mes recherches portent sur l'écologie quantitative et l'écophysiologie, et en particulier sur la modélisation des réponses des plantes aux facteurs environnementaux et sur la prédiction de l'adaptation des arbres aux changements climatiques. J’utilise des outils scientifiques qui impliquent les observations de longue durée récoltées dans des parcelles permanentes sur de vastes régions géographiques, les expériences de manipulation en nature, la migration assistée d'écotypes et les designs expérimentaux dans des milieux contrôlés. Mes projets actuels portent sur la dynamique de croissance et de reproduction des arbres à échelles spatiales variées, de celle locale à celle globale, et sur la prise en compte des effets du changement climatique sur la productivité forestière par les nouvelles stratégies d’aménagement. Je suis considéré comme l’un des pionniers des études sur la formation du bois dans les écosystèmes tempérés et froids et d’écotones de la limite de la forêt. J'ai réalisé plusieurs méta-analyses sur le calendrier intra-annuel de croissance des arbres à travers l'hémisphère boreal.
