Research Interests

Plant breeding is currently facing new issues related to global warming and the need to limit environmental impacts of agriculture. Many traits of interest in plant breeding have a complex genetic architecture that is still poorly known. Development of genotyping, then sequencing approaches as well as the access to new other “omics” information make it now possible to better decipher trait architecture and to develop new breeding approaches. My main subjects of research are related to the development of methods and experimental designs for QTL (Quantitative Trait Loci) detection and marker-assisted selection, with a specific focus on multiparental and hybrid designs and applications on Maize. With the advent of high-throughput genotyping approaches, my subjects of research are now more specifically oriented towards:

Most of my research is done in collaboration with private breeding companies mostly on Maize but beyond Maize my objectives are to develop methods and tools applicable to other species, such as “OptiMAS”, a decision tool for implementing marker-assisted selection. Beyond Maize, I am therefore also contributing to projects on different other species (Tomato, Cucumber, Linus, Legumes…).

Main ongoing / recent project responsibilities and community implication

*I give lectures on QTL detection, Marker-Assisted Selection and Genomic Selection to different Masters in AgroCampus Ouest, AgroparisTech. I contribute to the Master of plant Breeding of the CIHEAM, Zaragoza, Spain on the interest of Biotechnologies in Maize breeding. *I also regularly contribute to courses given for scientists from public institutes or private companies organized by ASFIS, with the framework of projects (Amaizing, Selgen) or organized internally by private breeding companies on QTL detection/GWAS/MAS/GS.
