Host-symbiont interactions and insect communities provide ideal models for investigating diverse evolutionary and ecological processes. 

At the ISEE lab, we try to explain the observed variations in prevalence and penetrance of a Wolbachia infection in insect populations. In particular, we investigate how symbiotic micro-organisms may influence insect communities and food-webs, and how the diverse interactions between species of insect communities may facilitate the horizontal transfer of their endosymbionts.
