Je travaille sur l’écologie et l’évolution des systèmes de reproduction chez les plantes, avec un intérêt particulier porté d’une part aux causes et conséquences de l’évolution de l’unisexualité et d’autre part à la communication entre plantes et pollinisateurs. J’utilise des approches de terrain, modélisation, génétique des populations, génétique quantitative et écologie évolutive, écologie chimique.

Voici un échantillon des questions auxquelles je tente de répondre :
