J'étudie le rôle de la médiation chimique dans le fonctionnement de différents types d´interactions plantes-arthropodes. J'ai pour objectif de caractériser l´impact de l’augmentation de polluants atmosphériques sur la rencontre entre espèces dans les interactions plantes-insectes et donc sur la résilience de ces interactions. J'étudie également les mécanismes évolutifs expliquant la nature des signaux chimiques ainsi que la détection de ces signaux dans les interactions plantes-pollinisateurs.


I study the role of chemical mediation in the functioning of different types of plant-arthropod interactions. I aim at characterising the impact of increasing concentrations of atmospheric pollutants on the encounter between species in plant-insect interactions and hence on the resilience of these interactions. I also investigate the evolutionary processes explaining the nature of the chemical signals and how they are detected in plant-insect interactions.
