My research group focuses on rivers.  The bulk of our work is focused on river science ranging from hydrology and sediment transport to biogeochemistry to landscape genetics.  Our work has ranged from local studies of flood waves and invertebrates in the local drainage ditches, to tidal stream ecosystems on the Coast of North Carolina, to floodplain foodwebs along the Danube River.

We also try to understand the context for river science in society.  We work on policy implications of river restoration at small scales, how emerging economic incentives affect river management, and how river management practices are being affected by subtle changes in climate in the Southeastern US.

Much of my current work focuses on how river governance works; we have begun looking in detail at the policies and practices of the Corps of Engineers, the Bureau of Reclamation, and several state environment and water agencies, trying to better understand water and society and governance.
