My activity

I am interested in understanding the link between the evolution of phenotypes and adaptations at the molecular level. More precisely, I am studying convergent adaptation to myrmecophagy (ants and/or termites’ consumption) in placental mammals (aardvark, anteaters, armadillos, pangolins, and aardwolf). I am using comparative genomics and metagenomics approaches. To characterize genomic adaptations linked to this diet, I am interested in the evolution of three gene families: mucins (MUCs), olfactory receptors (ORs) and taste receptors (TASRs). I am also studying the role of the gut microbiome. Using metagenomic sequencing data of faecal samples, I aim to identify microbial species and to reconstruct their genomes to characterize metabolic pathways of chitin degradation to understand the role of microbial species in preys’ digestion.
