- Systematics of the Pentatomoidea, especially the Pentatomidae
- Molecular Genetics
- Ecology of the northern tallgrass prairie arthropods
Much of my work focuses on nomenclatural issues, including the development of world catalogs of all pentatomoid families. My laboratory is in the process of setting up a molecular genetics laboratory. This will allow us to use molecular data to help infer phylogenetic relationships, and thus prepare a new, more natural classification.
