I received a Ph.D. in Population biology and Ecology from the University of La Réunion (France) in 2017 and I am currently working in the Adaptation to heterogeneous Environments subgroup of cE3c. My research focus on the niche width of phytophagous species and the differences between their fundamental and realized niche. I did my PhD on the host specialization within a community of fruit flies (Diptera: Tephritidae) in a French tropical island. I am currently working on the individual variation of the niche width using spider mites (Tetranychus sp). My main goal is to understand differences between specialist and the generalist strategy.
