Research Interests

My research focuses on the measurement and modeling of terrestrial water storage and its components, including ground water, soil moisture, snow, and surface waters. I am particularly interested in deriving hydrological information from Gravity Recovery and Climate Experiment (GRACE) satellite observations of Earth’s time variable gravity field, and I am a member of the GRACE science team. I also lead the Global Land Data Assimilation System (GLDAS) project, which aims to produce high resolution, optimal output fields of land surface states (e.g., soil moisture and temperature) and fluxes (e.g., evapotranspiration) by parameterizing, forcing, and constraining (via data assimilation) sophisticated numerical land surface models with data from advanced ground and space based observing systems. Improved understanding of variability in the stocks and fluxes of terrestrial water has implications for weather and climate prediction, water management, agricultural applications, natural hazards (e.g., floods and biohazards), and military mobility. My newest research thrusts include quantifying ground water’s role in the Earth system and using our data-integrating models for water resources applications.
