Research Interest

I am an ecophysiologist interested in the interactions between legumes root and soil microbial communities. My goal are to (1) characterize rhizodeposition fluxes and (2) identify the mechanisms that modulate these fluxes in response to environmental conditions and as a function of crop genotype. The combination of these approaches aims to (3) build a mechanistic understanding of rhizodeposition and its trade-off with productivity and resilience in the whole rhizosphere – plant continuum. On-going research efforts focus on axis (1), while methods are currently developed for axis (2) which will be pursued later.

Previous experiences

My Ph.D. project focused on the physical and molecular bases of the vulnerability of plants to cavitation during drought episodes.

My postdoctoral experience focused on non-structural carbohydrate (NSC) storage in wood and its implications during dormancy and spring resumption of growth.
