Research and Extension Areas: (Soils & Water Quality)

Dr. Dennis current Research and Extension work spans water resources and environmental soils. His research and extension work pertains to surface water monitoring for nutrient contaminants and sediments at the watershed scale. He has been involved in coordinating regional technology transfer conferences and multi-state training programs that have educated and increased the capacities of water resource management professionals across the region and nation. He is also involved in multi-state program teams that target critical issues in nutrient management, irrigation management, animal waste management and runoff management in watersheds across the south.
