My research interests encompass several aspects of evolutionary biology and population genetics and genomics.
INRAe offered me a permanent researcher position in 2019 at the CBGP institute in Montpellier to work on population genomics. I mainly ask applied scientific questions for the management of several species of pest insects and fish species that are either in expansion (i.e. Pine processionary moth, American cocoa pod borer) or invasive (i.e. Mosquitofish, Box tree moth).
During my second and last postdoc, at CNRS, CEFE institute in Montpellier, from 2015 to 2019, in collaboration with Anne Charmantier, I used a combination of population genomics and quantitative genomics, based on genotyping by sequencing and phenotyping in wild populations, to investigate local adaptation and morphological traits variations in several blue tits and great tits populations.
During my first postdoc, in Université Laval, Quebec City, in collaboration with Louis Bernatchez, from 2011 to 2015, I used genetic and genomic tools to study population genetics, landscape genetics, and local adaptation in Atlantic salmon, lake trout and brook trout.
During my PhD at INRAE in Rennes, supervised notably with Guillaume Evanno, I was mainly interested in measuring the effects of restocking on population genetics and evolutionary dynamics of Atlantic salmon populations in France.
