Research

The goal of my research program is to develop and implement cost-effective reduced-risk Integrated Pest Management (IPM) practices for irrigated crops in eastern Oregon, including potatoes, onions, corn, wheat, etc.  This goal is achieved through the integration of population dynamics studies, understanding insect behavior, and implementing biological and chemical control  methods.  My extension program delivers IPM information to growers, crop consultants, field experts, and  public in general following "one to one" approach, and developing on-farm demonstration trials, presentations, trainings, workshops, and extension publications.

Outreach and Extension

Extension Research: My appointment is 75% extension and 25% research. I am interested in developing an Ecological Based-Integrated Pest Management (IPM) program in various crops. My area of expertise encompasses biological control, insect biology, ecology, and population dynamics; both basic and applied (field and greenhouse production). Crops I have worked with include potato, sweet potato, asparagus, cotton, corn, soybean, alfalfa, wheat, strawberry, and vegetables. My major responsibilities as an Extension Entomologist at OSU are to attend emergencies in irrigated crops such as potatoes, grasses, onions, carrots and others in Eastern Oregon.
