Research interests

As a plant ecophysiologist, I’m particularly interested in 1. tree carbon functioning especially in the woody parts (ring growth, reserve dynamic, stem respiration and stem photosynthesis, tree-soil carbon allocation) 2. stable carbon isotope composition (13C/12C) in leaves and rings and its drivers, 3. tree responses to drought and climate variations (including sometimes tree decline). My approach is based on experimental studies both in the field on mature forest trees and on smaller potted plants.

Since 2013, I’ve been carrying out art-science projects about intimacy with trees in collaboration with artists. I also currently develop an interdisciplinary approach of the human-nature relationship at the individual level by providing links between ecology, art, anthropology and, philosophy.

Key words: tree ecophysiology, forest tree, carbon, growth, reserve, stem photosynthesis, 13C, rings, drought, functional adaptation, art-science, human-nature relationship.
