Research Interests -Ecohydrology, solute and sediment transport at various spatial/temporal scales, development and assessment of best management practices to minimize nonpoint source pollution, spatial variability of natural processes that control hydrologic/water quality watershed response, effect of land use on sediment, nutrient and metal transport, interaction of terrestrial and aquatic processes affecting water quality and linking these processes to develop integrated watershed/water quality management technology, mathematical modeling of sediment, nutrients and metals at different spatial scales, and application of geographic information systems and remote sensing in developing decision support system for ecosystem management.
