Research Interests
Support, design, and develop research projects principally in applied entomology. Projects support the management of insects of importance for field crops and range in western Nebraska. Current focus crops include corn, wheat, sunflower, dry bean, and sugar beet.

Extension Interests
Develop and deliver educational media and programming for insect management for field crops and rangeland common to western Nebraska. Media include the delivery and development of online media as well as decision support and information systems. Crops include corn, wheat, sunflower, dry bean, potato, and sugar beet. In rangeland the focus is on sustainable rangeland management.

Major Project Activities
  • Evaluating biological control of the wheat stem sawfly
  • Development of biological control strategies for the management of pests of dry edible beans
  • Evaluating the role of soil arthropods in soil health
  • Development of IPM strategies in sunflower
