Broadly, I am interested in how herbivorous insects respond to some of the selection pressures they encounter in their environments. Recently, this has focused on the population genetics of the western corn rootworm Diabrotica virgifera virgifera in relation to the adaptation of this important agricultural pest to crop rotation as a management tactic and the species’ potential to adapt to transgenic corn. I also have an interest in understanding the extent to which alternative host plants affect the genetic structure of insect populations.
I am currently developing a research program that will address some of the molecular processes involved in insect-plant interactions. This program aims to investigate the genes and gene products that enable insect herbivores to cope with the many potent defensive secondary metabolites and macromolecules that plants produce in response to insect feeding.
Another area of interest is the use of population genetics approaches to study species that are invasive or expanding their existing ranges into new territory.
I teach Insect Physiology in the Spring semester of even-numbered years and Population and Ecological Genetics in the Fall Semester of odd-numbered years.
