Bio	My primary research interests are in electronic sensors and instrumentation, with application in biological and agricultural production systems. Specific areas of work have included post-harvest engineering in fruit production, biosensors for dairy production, and biological control of insect pests. Post-harvest research projects have been done on machine vision systems for sorting fruits, vegetables, and flowers, and nondestructive fruit firmness sensors. Several current or recently completed research projects serve to illustrate these activities: A Machine Vision System for Fruit Defect Detection in Real-Time Spray Application of Insect Pheromones in Biodegradable Carriers for Mating Disruption A Biosensor for Measurement of Bovine Progesterone During Machine Milking
