Research interests

Evolution of mechanisms of sex determination and modalities of action of feminizing factors.

Targets of Wolbachia: evolution of specificity of the gene encoding androgenic hormone in isopods, impact of Wolbachia on the regulation of this gene expression during development. Study of neuropeptides involved in major physiological functions of crustaceans (e.g. crustacean hyperglycemic hormone and vitellogenesis inhibiting hormone).

Modalities of action of feminizing factors: study of the type IV secretion system (T4SS) (functional and phylogenetic approaches), isolation and characterization of virulence factors (ankyrin-domain proteins, phage-related factors…), characterization of Wolbachia genome (evolution of bacterial genomes, genomic plasticity and role of mobile genetic elements).

Keywords: androgenic hormone, CHH, VIH, T4SS, ankyrin gene, bacteriophage, bacterial genome.
