My interest is in developing methodologies and computer simulation programs that help in understanding the availability of water resources in arid and semiarid regions.

My research includes developing regional conjunctive use models (groundwater, surface water, landscape), parameter structure identification (model calibration), mathematical optimization strategies for sustainable management of water resources, and reservoir operations and management.
