Research Topic

As a geneticist, I’m interest in the consequences of the domestication process at the genome-wide level in plant and animal species of economical interest. I trained in quantitative genetic and molecular biology during my PhD and turned to population and evolutionary genetic and bioinformatic as well.

Within the Qualitom team (Quality, Diversity and Environment in tomato), I use the tomato crop (Solanum lycopersicum) and its wild relatives to (1) characterize the genetic resources; (2) to detect the footprints of the domestication at the nucleotide and gene expressions levels; (3) identify the genetic bases of traits of economical interest using association genetic (GWAS) and (4) evaluate the genomic selection strategy in this crop.
