Current areas of research include 1) interactions between bottom-up forces (plant defenses) and top-down control (predators and parasitoids) of herbivores, 2) the influence of plant defenses on a community of organisms including insects and pathogens, and 3) the ecology of fear, how herbivores behaviorally and physiologically respond to the presence of predators. This research is conducted using crop plants in agricultural settings as well as their wild relatives in natural communities.
