My current research focuses on wetland processes and functions, including the dynamics of energy flow and nutrient transformation in wetlands, the fate and effects of contaminants in wetlands, and the role of wetlands in watershed hydrology and water quality. Much of my effort is directed toward developing and applying performance forecast models for siting, design and assessment of wetland restorations in agricultural watersheds. We have developed one of the nation’s most comprehensive datasets on the performance of wetlands in agricultural landscapes and have shown that wetlands can significantly reduce agricultural nitrogen loads if those wetlands are strategically sited and correctly designed.
