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 or range expanding species and the way they fit to 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 the process of range ex­pan­sion drive to evo­lu­tio­na­ry changes and syn­dromes?
• what is the role of plas­ti­ci­ty (phy­sio­lo­gi­cal, tro­phic, etc.) in the co­lo­ni­za­tion of new en­vi­ron­ments?
• do in­va­ders and native range expanders 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 and 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 longhorned beetle (Anoplophora glabripennis) and the box tree moth (Cydalima perspectalis).
