I have three interrelated research interests.
- I study arthropod behavior and ecology, and have published work on caterpillars, butterflies and spiders. Currently I am working with Lincoln Brower to understand why monarch butterflies are so selective about their wintering sites in Mexico. I am also investigating sexual selection and sperm competition in the northern walkingstick insect, Diapheromera femorata.
- I am fascinated by, and concerned by, the effects of invasive organisms on the ecological communities they invade. Two plants that my students and I have examined on Sweet Briar's campus are Japanese stiltgrass, Microstegium vimineum, and periwinkle, Vinca minor. My interest in invasive species has broadened to encompass student research on exotic plant pathogens, parasitoids, earthworms and crayfish.
- As a field biologist on a 3200-acre campus, I conduct research on the ecology of our hardwood forests, open fields and freshwater habitats.

Recent student research projects
I supervise research on the ecology, natural history, and behavior of organisms in the wild; and on animal learning in the lab. Many students work on insects, but I also supervise research on salamanders, crayfish, plants, reptiles and fish. As long as I feel that I have enough expertise to supervise a project, I enjoy learning along with my students.
