I have been teaching at the university level and conducting field and laboratory research since 1997, primarily on fishes. I have experience in aquatic sampling across much of eastern North America. My work history includes employment as a Conservation Forestry Aide, Fisheries Technician, and Fisheries Staff Biologist with the Missouri Department of Conservation. I have served as a Teaching Assistant, Assistant Professor, and Associate Professor at four universities, and presented and published research with undergraduate students.
