He then relocated from Texas to California where he was employed by a crop protection company. Returning to school again after several years, he studied weed science at Colorado State University and received his doctorate in 1998. Dr. Miller has taught online Biology and Botany classes for the Colorado Community Colleges Online (CCCO), and currently offers “Weed Management and Control” as well as “Elements of Ecology” courses through Colorado State University.
