Research Specialization

Evolution and Ecology of Plant-Herbivore and Plant-Herbivore-Natural Enemy Interactions.  Most herbivorous arthropods are highly specialized and feed upon only a few of the host plant species available to them. We seek to better understand how such non-random associations evolved, are maintained, and vary in space and time. Our research ranges widely over many systems. We are particularly interested in learning the genetic basis of variation in the suitability of plant populations to support local insect populations. We also are interested in better understanding the genetic basis of the adaptations of insect populations to those plants A strong emphasis of my research also is in learning how host plant chemical variation affects the relationships between herbivores and their natural enemies.
