I am a Research scientist working at the Forest Zoology Research Unit (URZF), INRA Orléans, France.
My research interests lie in the relationship between the durable success of invasive species and the way they fit the novel selection regimes encountered as they expand and/or disturb colonized habitats, as well as the facilitating effects of climate change. Such adjustments result from plastic and evolutionary changes, which I investigate using both field and experimental approaches (mainly tools in ecophysiology, metabolomics and morphometrics). I aim to address questions such as:
- how does range expansion by itself drive to evolutionary changes and syndromes?
- what is the role of plasticity (physiological, trophic, etc.) in the colonization of new environments?
- do invaders have scope to persist over the long term despite the ecological perturbations induced by their own residence?
I have been working several years on invasive or endemic insects of the sub-Antarctic islands, and now focus on the climate change induced northward range expansions of the pine processionary (Thaumetopoea pityocampa) moth across Europe, as well as of the winter moth (Operophtera brumata) in northern Fennoscandia. I also contribute to projects on the European invasions of the Asian longhorn beetle (Anoplophora glabripennis) and the box tree moth (Cydalima perspectalis).
