My research focuses on flow and transport within surface water systems, including rivers, streams, lakes, fresh-water wetlands, and salt-water marshes. I am particularly interested in coupling improved understanding of small-scale physical processes pertaining to turbulent boundary layers and aquatic canopies to larger scale modeling and prediction. This work is fundamental yet also has clear applications, reaching into real-world management issues including stream restoration, constructed treatment wetland design, aquaculture, and suspended sediment pollution control. In addition, it is at the interface of hydrology and a wide variety of other disciplines, including fluid mechanics, geomorphology, ecology, water resources, and oceanography.
