Genetic variability of maize adaptation to drought and high temperature, impact on performance and breeding strategies
Direction Montpellier Plant Phenotyping Platform (M3P)

I joined LEPSE INRAE Montpellier in 2003 to develop a programme at the interface between genetics and ecophysiology after having led work on maize genetic diversity and adaptation to tropical acid soils (1992-2002).
I am working on the genetic variability of maize adaptation to drought and high temperatures, its impact on performance in scenarios and consequences for breeding strategies. I conduct this work in the framework of large academic/private consortia. Since 2012, I am co-director of the phenotyping platform M3P.

Projects, expertise and collaborations

I am currently involved in several national and international collaborative projects on climate change adaptation in the framework of large academic/private consortia (PIA-AMAIZING, H2020-INVITE,...) and research projects in phenomics and development of phenotyping infrastructures at national and European level (PHENOME, EPPN2020,...).
I am a scientific expert at the CTPS (Comité Technique Permanent de la Sélection des plantes cultivées). I am a member of the scientific councils of the INRAE experimental units of St Martin de Hinx (maize experimental farm) and Mauguio (DIASCOPE) as well as of the Maize Biological Resource Centre.
