My research focuses on hydrology and water resources, especially understanding rainfall-runoff processes through observation and modeling at a watershed scale.
I am particularly interested in soil moisture, how it controls water cycles, how to represent the process in modeling, and how to leverage the simulation results for flood and drought management.

Keywords
hydrology, surface-subsurface processes, soil moisture dynamics,
climate and land-use impacts, flood and droughts
