My current research aims at:

•Understanding how the management of intra-specific diversity in crops can contribute to a better performance of crops, and more specifically study the effect of plant to plant interactions in wheat cultivar mixtures, through experimental approaches as well as development of models coupling ecophysiology and genetics;

•Developing appropriate models in quantitative genetics to study the mixing ability of genotypes and contribute to the development of original breeding schemes for plant teams, both within and between different crop species;

•Mobilizing participatory approaches to co-design mixtures delivering appropriate services from farmers to end-users;

•Studying the impact of the managementof disease resistances on the evolution of virulence of pathogen populations, focusing on wheat cultivars deployment in Europe and the selective pressure produced on rust fungal populations.
