My research focuses on adaptations that facilitate host-switching in plant associated insects. In particular, I am interested in characterizing the interaction between insect traits, competition, and host traits using phylogenetic comparative methods. My study system consists of many New World fig species (Ficus, Moraceae) and their associated pollinating and non-pollinating fig wasps (Chalcidoidea). Improving our understanding of how various adaptations allow insects to develop novel host relationships and co-evolve has significant relevance for understanding the origins of biodiversity, as well as for agricultural pest management.
