I teach courses in agricultural energy and off-highway vehicle design, and I co-advise our department's ASAE ¼-Scale Tractor Design Competition team. Previous research projects have included in diesel engine durability using biodiesel, tractor engine-transmission control systems, development of grain flow sensors for yield mapping, and energy use in agriculture. More recent projects have included systems for efficient application of anhydrous ammonia fertilizer and a system for dispensing grain tracing caplets on a combine.
