My research interests encompass several aspects of evolutionary biology and population genetics and genomics. 

I started in october 2019 to work at INRAe, at the CBGP institute in Montpellier, working on population genomics in insects, birds and fishes.

During my postdoc at CNRS, CEFE institute in Montpellier, I used a combination of population genomics and quantitative genomics, based on genotyping by sequencing and phenotyping in wild populations, to investigate local adaptation in several blue tits and great tits populations, in collaboration with Anne Charmantier (CNRS, Montpellier).

During my first postdoc in Quebec, in collaboration with Louis Bernatchez (Université Laval), I used genetic and genomic tools to study popualtion genetics and local adaptation in Atlantic salmon, lake trout and brook trout. 

During my PhD at INRAE in Rennes, in collaboration 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.
