Robert Coulson, Ph.D. is a professor in the Department of Entomology. He joined the Texas A&M University System as Principal Entomologist with the Texas Forest Service and Assistant Professor with the Texas Agricultural Experiment Station. Subsequently, he received an academic appointment with the Department of Entomology at Texas A&M University. Dr. Coulson's research has been transdisciplinary in approach and directed to investigations of the activities and impacts of insects and other taxa in forest, prairie, savanna, agricultural, and urban landscapes. The research addresses issues of significance to ecological science as well landscape-use management. In 1984 he co-founded the Knowledge Engineering Laboratory (KEL) to facilitate research and development of computer applications for planning, problem-solving and decision making in environmental science and management. Focus of KEL research is directed to landscape-scale problems that require integration, interpretation, and use of different representations of knowledge. Special emphasis has been placed on ways and means of blending qualitative heuristic knowledge of experts with quantitative information that results from scientific investigations.
