Research interests

Soil scientist fascinated by plant ecophysiology, my research focusses on soil-plant interactions in both natural and controlled conditions. I am particularly interested in silicon (Si), a major component of the Earth’s crust and soils, that is increasingly considered as a key element in plant ecology and agriculture through the fantastic process of biosilicification (mineral deposits in plant organs as seen on the left).

 

 

Research thematic

I combine expertise in soil science and plant ecophysiology to work on three different research axes:

  • The influence of soil properties, and in particular their evolution over time through the use of long-term chronosequences, on silicon cycling (e.g., soil Si pools and fluxes, Si availability for plants, Si uptake by plants and silicification, biological versus lithological control on Si cycling)
  • The control of overlooked biotic factors on soil-plant Si mobility (e.g., soil microorganisms, large herbivores, root exudates), and how they could be leveraged to increase crop Si status through specific agricultural practices.
  • Developing functional trait-based approaches to better understand the role and functions of Si and silicification in plant ecophysiology, and how it aligns with major ecological theories (plant growth/defense tradeoff, plant economics spectrum, resource availability hypothesis, etc.).

I am interested in the diversity of adaptive strategies in plants. My work mainly focuses on the ecological causes of the maintenance of phenotypic variability at the intraspecific level.

Taking advantage on the one hand of high-throughput phenotyping facilities, and on the other hand of the extensive genetic resources available in model and crop species, I aim at:

- caracterizing the functional trade-offs that shape evolutionary adaptation (economy of resources, growth-defense, allometry) both between and within species

- evaluating the genetic bases of these trade-offs (QTL, GWAS) and their evolution (molecular signatures of selection, genomic, population genetics)

- examining how growth, survival and reproductionvary along these trade-offs depending on the environmental conditions

A l’interface entre écologie fonctionnelle et écologie des communautés, je cherche à comprendre les causes de variation de la biodiversité, aussi bien à l’échelle locale que continentale, et l’effet de changements de la biodiversité sur la dynamique et le fonctionnement des écosystèmes.
