specialist in plant physiology. I conduct research on the hydraulic functioning of plants in relation to drought resistance. Since my training, my research work has focused on the response mechanisms of plants to environmental stresses, initially on herbaceous species (tomato, sunflower, Arabidopsis), using mainly molecular and biochemical approaches (plant transformation, transcriptomic and proteomic analyses, enzymatic and biochemical assays, etc.). Since I have been a lecturer at the UMR-PIAF in 2005, I have been studying the determinisms of tree response to environmental stresses. I join the SurEau team created in 2007, whose research focuses on the physiological and genetic determinants of the hydraulic architecture of trees and the implications for their resistance to drought. I have broadened my skills in tree ecophysiology, in particular in xylem hydraulics, to develop approaches aimed at disentangling the anatomical and molecular bases of xylem hydraulic safety traits, their variability and their relationship with drought tolerance.
