Research Interest

Judith Becerra, PhD, is an evolutionary ecologist interested in insect-plant interactions. Her current research combines ecological, biogeographycal, and chemical information with molecular phylogenetics to identify macroevolutionary patterns of host shifts, co-adaptive forces shaping coevolution and evolutionary strategies of plant chemical defenses. She is also interested in plant and insect diversification and ecological chemical interactions between insects and plants. Extensive research has been pursued in the Mexican tropical dry forests with the plant genus Bursera and their herbivores, the beetle genus Blepharida. These two groups have interacted for the last 100 million years and are both highly diverse, with spectacular adaptations and counteradaptations.
