About Derek Heeren
Derek leads a research and teaching program at UNL which focuses on irrigation engineering and vadose zone hydrology. He obtained his doctorate while working as a Research Engineer in the Biosystems and Agricultural Engineering Department at Oklahoma State University. He received his bachelor’s and master’s degrees in agricultural engineering from South Dakota State University. Before graduate school, Derek spent two years working at a geotechnical engineering firm in the St. Louis, Missouri, area. Derek grew up in southeastern South Dakota on a farm that included corn, soybean, alfalfa, dairy, and beef production. During high school he developed an interest in conserving natural resources while participating in FFA land judging and natural resources competitions.
