My research program includes engineering aspects of harvesting and post-harvest processing systems (handling, drying, and storage). My research examines how sensors and agricultural data can be leveraged to allow producers to make better decisions, and to develop system models to improve the efficiency and sustainability of production.

Related to harvest logistics, my work explores issues related to harvest timing and losses. This includes developing models for grain harvest systems and applying site specific weather information to develop models for crop dry down. I am also exploring applications of sUAS to identify areas of a field with damage, specifically focusing on lodging in corn.

Specific research focuses related to grain inventory include better quantifying grain handling losses and calibration of a science-based model for determining packing of grains in upright storage structures. Other post-harvest grain management interests include evaluating fan control strategies for natural air drying.
