Study Director:


Dr. George M. Hornberger - (Chair)
Vanderbilt University

George M. Hornberger, Chair, NAE, is a Distinguished University Professor in the Department of Civil and Environmental Engineering and the Department of Earth and Environmental Sciences at Vanderbilt University. His research interests are catchment hydrology and hydrochemistry, as well as the transport of colloids in geological media. His work centers on the coupling of field observations with mathematical modeling, with a focus on understanding how water is routed physically through soils and rocks to streams and how hydrological processes and geochemical processes combine to produce observed stream dynamics. This modeling work allows the extension of work on individual catchments to regional scales and to the investigation of the impact of meteorological driving variables on catchment hydrology. Dr. Hornberger is a member of the American Geophysical Union, the Geological Society of America, the Society of Sigma Xi, and the American Women in Science.
