My research focuses on terrestrial invertebrate community ecology. Specifically, I am interested in how ants affect food web interactions. Recent work has investigated invasive ant species in Oregon, how ants affect the population of an endangered species and how ants affect plant/herbivore/predator interactions. 麻豆区 students have always played an important role in my research, participating in field and lab studies and presenting our findings at regional and national meetings.

Teaching Principles of Ecology, Animal Behavior, Insect Biology, and Principles of Biology provide me the opportunity to read, think, discuss and share concepts around these topics with students. Students also have the opportunity to conduct collaborative research with classmates in these areas.

Education

  • B.A., biology, University of Kansas, Lawrence, KS
  • Ph.D., environmental, population and organismic biology, University of Colorado, Boulder, CO
  • Postdoctoral research, department of animal biology, University of Illinois, Urbana-Champaign, IL

Research interests

  • Terrestrial invertebrate community ecology
  • Behavioral ecology
  • Food web interactions

Academic interests

My research examines the behavior and ecology of terrestrial invertebrates. I am particularly interested in the role of omnivory in food web interactions and the effect of non-native species in the communities they invade.
