I am the IIHR Director, a professor of civil and environmental engineering, and hold the Edwin B. Green Chair in Hydraulics. With Director Witold Krajewski, I helped create the IFC and continue to be active in its development through work with the Iowa Legislature. I have also been active in IFC programs for statewide floodplain mapping and watershed projects for flood damage reduction, including the $97M Iowa Watershed Approach. As a service to the state of Iowa, I am a member of the Water Resources Coordinating Council and participate on numerous state and federal agency committees related to water resources planning. I frequently present to community groups on water resources-related topics. I am a native Iowan and enjoy outdoor activities, including fishing, hunting, and woodland restoration and conservation work.
