Understanding Integrated Modeling and Conjunctive Use of Water 
through New Software Developments and Applications

Biography

USGS California Water Science Center Hydrologist since May, 2010.

-------------------------------------------------------------------------------

My primary research interest is in understanding water resources through the use of computer software and applied mathematics.

My research encompasses analyses of regional flow systems with the development of new software, concepts, and supporting mathematics. Extended areas of research include operations research such as Bayesian and deterministic inverse problems, mathematical data assimilation, and techniques that reduce the computational burden of solving these problems, such as POD model reduction. These new methods help to better understand the hydrologic cycle and to develop more process-based hydrologic simulation tools that help water-resource managers with operations, planning, and policy issues.
