|Appointment: 50% Extension, 50% Research
Professional Responsibilities and Activities: My lab is focused on integrated pest management of field crops and range common to western Nebraska or the High Plains ecoregion of the United States. Our lab is trying to understand the interactions of management practices common to this ecoregion on insect abundance, distribution, and biology, and the diseases related to these interactions. Areas of study include: plant resistance to insects, insect movement, and insect-vector biology. Crops of interest include: Wheat, corn, sugarbeet, dry edible beans, sunflower, and potato as well as range. My lab is striving to integrate mobile and social-networking technologies into Extension programming and to facilitate real-time technology transfer of regional research efforts.
