Self-introduction
I specialize in watershed hydrology, environmental science, and ecology, focusing on the impacts of urbanization, agriculture, forest growth, and climate change on water and nutrient dynamics. By integrating modeling and remote sensing, my work addresses nitrogen–phosphorus cycling and groundwater–surface water interactions. Currently, I am exploring coupled water–material–nutrient processes and developing AI-integrated digital twin approaches for sustainable water management. I also serve on the Early Career Editorial Board of Earth.
