The main aim of my research is to improve our understanding of the evolutionary processes acting on genes and genomes. The integrative nature of our research is pivotal and involves multiple cross-talks between theoretical and empirical analyses, and extends to functional genetic approaches to explicitly validate the role of the observed polymorphisms.

Our recent research used closely related Arabidopsis species (A. halleri, A. lyrata et A. thaliana) and focused on self-incompatibility, a textbook exemple of natural (balancing) selection. This work led us to extend our investigations to broader questions in evolutionary genomics such as the acquisition of evolutionary novelty, the evolution of gene regulation and dominance/recessivity interactions, the dynamics of transposable elements across the genome or gametic segregation distortion. More recently, I have also become interested in the evolution of reproductive systems in the Oleaceae family.
