Presentation :
I work as a junior researcher at the INRA Jouy-en-Josas campus in the Mathématique, Informatique et Génome laboratory (MIG). I am mainly interested in evolutionary genomics with a special interest in robust phylogenetic inferrence, outlier detection in evolutionary studies (rogue taxa/influent sites), phylogenetic comparative methods (linking genotypes to phenotypes). I'm also interested in metagenomics, with a special interest in models for metagenome evolution (using adequate representation of a metagenome) and statistical modeling of biological networks (using mixture models).
