Research

Postharvest engineering, handling (storage, drying, etc.), traceability, and processing of agricultural commodities with a goal of reducing energy consumption while ensuring food quality and safety. These are critical issues for the fresh market fruit and vegetable, dried fruit, tree nut, and rice industries in California and the World.
