More than 80% of the ~300,000 species of angiosperms on Earth exhibit adaptations for pollination by insects, and thus most terrestrial ecosystems depend on insect pollination services. Nonetheless, our understanding of how plant-pollinator mutualisms diversified, coevolved, and assembled into ecological networks remains surprisingly limited. Our research focuses on understanding the ecological, evolutionary, and genetic mechanisms of adaptation among plant-pollinator mutualisms. We integrate genomic, chemical, and behavioral approaches to elucidate the evolutionary origin and the ecological function of both insect and plant adaptations.
Evolution, adaptation, and speciation of plant-pollinator mutualisms. Comparative and population genomics of bees and their associated host plants. Phylogenetics, chemical ecology, neuroethology, and natural history of insect-plant interactions.
