My research targets coupled biological and physical variables in river and estuarine systems. I am particularly interested in flow and sediment interaction and their influence to aquatic organisms at multiple scales. I study both natural hydrologic phenomena as well as waterways that are modified for human benefit; for instance by, dams, dredging, levies and hardened structures. Applications for my research include development pathways and infrastructure that minimize ecosystem disruption and promote preservation or restoration of aquatic ecosystem services.
