My professional interests include riparian ecology, management and restoration, especially in agricultural landscapes, hydrology and soils, agroforestry. My research emphasis focuses on the design and function of riparian management systems that reduce the movement and remediate the impact of non-point source pollutants from croplands and pastures to adjacent streams. Presently we are also studying the impact of riparian buffers on stream bank stability and quantifying the proportion of stream sediment that originates from bank erosion and surface erosion.
