Biography

My educational background consists of studies that focused on agricultural/horticultural sciences. I have a B.S. degree in Agronomy, Masters' and a Ph.D. degree in Agronomy Sciences (Plant Production/ Weed Science). Also, an additional Masters' degree in Crop & Soil Science (Turfgrass/Weed Science) from Auburn University. Extensive experience and knowledge of managing crops, horticulture, turfgrass, and weeds in a wide range of environments.

My current research and crop responsibilities center around Diversified Agricultural Systems Farms, including horticulture crops, commercial fruit, and nut crops, and weed sciences exploring chemical and organic options for weed control, improving pesticide application technology, drone use for data collection and pesticide application, and pollinator-serving plant communities.
