My research and training are in the areas of watershed hydrology, surface water quality, Environmental Engineering, and environmental information systems. I focus on the development of new technology to increase the understanding of environmental processes. This includes the use of Geographic Information Systems for data analysis and dissemination, observation systems and sensor networks, data models, development of information systems that support environmental observations, and modeling techniques for surface water hydrology and water quality. I have contributed to advances in the cyberinfrastructure available for hydrologic and environmental observatories. Software developed includes the Observations Data Model (ODM) and supporting applications for loading, visualizing, summarizing, querying, and editing observations data.
