Courses Taught

NRE 2010 Natural Resources Measurements
NRE 3105 Wetlands Biology and Conservation
NRE 3155 Water Quality Management

Research Interests

Nonpoint source pollution is the general area of my research. More specifically, that includes riparian zone restoration, analyzing the effectiveness of various best management practices, and evaluating models. I also continue to do research in wetland hydrology and water quality. I have a general interest in proper designs of water quality monitoring studies and have written a book on the subject.
