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.

I am currently seeking a graduate student in Natural Resources and Earth Systems Science or Civil Engineering to start in Spring or Summer 2011 to examine feedbacks between fluvial morphodynamics and pioneer riparian vegetation in sand-bed rivers. This project will couple laboratory experiments, field investigations, and numerical modeling of vegetation, flow, and sediment interactions to develop a mechanistic and predictive understanding of feedbacks at nested spatial scales ranging from individual plants to channel reaches. Please contact me for more information or if you are interested in applying.
