Expertise: Chemical Ecology, Tropical Ecology, and Amphibian Biology, with an emphasis on predator-prey interactions and aposematism
My research is broadly focused on the ecology and evolution of antipredator adaptations in animals, particularly chemical defenses and aposematism. I am especially interested in studying these defensive adaptations in vertebrates (mainly amphibians and reptiles) that acquire chemical defenses from their diet. Most of my research surrounds the study of brightly colored poison frogs and the arthropod prey from which they sequester alkaloid-based chemical defenses. My research program is highly integrative, involves a variety of comparative and experimental approaches (both field- and lab-based), and incorporates aspects of ecology, evolution, behavior, morphology, natural history, and frog and arthropod chemistry.
