Education:

B.S. - 1983 - Purdue University, West Lafayette, IN (Agricultural Engineering)
M.S. - 1985 - University of Illinios, Urbana, IL (Agricultural Engineering)
Ph.D. - 1989 - University of Illinios, Urbana, IL (Agricultural Engineering)

Research Interests:

Current programming focuses on research, development, and education in the field of agricultural machine systems with emphasis on chemical application technology. Programs emphasize engineering solutions that will enhance the efforts that Integrated Pest Management Programs have protecting the environment and reducing pesticide requirements. Related interests involve dynamic simulation, computer imaging, non-chemical pest control alternatives, and incorporating site-specific systems into pest control strategy management.
