I am a hydrologist interested in exploring how water and solutes move and react within watersheds, how these movements and reactions change with climate variability and land-use alteration, and ultimately how these changes impact terrestrial and aquatic ecosystems. I currently lead national and international projects on the developments of interdisciplinary approaches for water security assessments and watershed management, in collaboration with geochemists, ecologists, agricultural (and forestry) scientists, as well as water conservation and protection agencies. Through these works, we develop science-based evidence on the interaction amongst hydrological, geochemical and ecological processes to inform watershed management, planning and engineering designs with the end-goal of managing the environmental impacts of climate variability and land-use alteration on groundwater (and surfacewater) resources.
