> Research interests, accomplishment and expertiseheterosis

My current research interests are focus on the phenomenons of hybrid vigor and inbreeding depression. My main objectives are to investigate with a high resolution the genetic determinants of heterosis to address in particular (i) the respective roles played by overdominance and pseudo-overdominance and (ii) the contribution of structural variation (presence absence of genes) to heterosis relatively to other types of polymorphisms. I also investigate to which extent heterosis is related to the combination of complementary adaptation factors in parental materials. My research takes place within the French investment for the future Amaizing program, in which I lead the heterosis task in the WP5 and WP6 (www.amaizing.org).

My past work has been to investigate how the Metabolic Control Theory could lead to a biochemical model of heterosis based on the definition of dominance and overdominance as emergent properties of metabolic systems.

During my postdoctoral fellow in the PCV lab, I’ve worked on the plant response to heavy metal stress in the context of phytoremediation.
