I am a Re­search scientist wor­king at the Fo­rest Zoo­lo­gy Research Unit (URZF), IN­RA Or­léans, France.INRA

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 longhorned beetle (Anoplophora glabripennis) and the box tree moth (Cydalima perspectalis).
