Research interests

I’m an ecologist interested on the interactions between plants and their associated insect communities (herbivores, parasitoids etc.) and pathogens.

During my PhD, I focused on PLANT-INSECT interactions on the context of PLANT INVASION in order to understand some of the key factors underlying the invasive ability of certain plant species. During my postdoc, I focused on PLANT-FUNGI interactions to study multiple infections and within-host competition of the anther-smut fungi, responsible for castrating its host.

One of my research interests relates to insect behaviour and to the mechanisms underlying host selection and acceptation by Lepidoptera (e.g. moths and butterflies) and Hymenoptera parasitic wasps. During my formation, I have developed a taste for CHEMICAL ECOLOGY, particularly the cues (e.g. volatiles, contact cues) used by insects during their host searching behaviour. This knowledge is essential to evaluate the efficiency of weed and crop pest BIOLOGICAL CONTROL programs.

Now working in DEEIT team, I am conducting the risk assessment for non-target species of a stemborer parasitoid to evaluate the feasibility of using the parasitoid as a new biological control agent against the Mediterranean corn borer (ANR project COTEBIO).
