Associate Researcher at the Chinese Research Academy of Environmental Sciences, with research expertise in groundwater contaminant transport, soil–groundwater pollution prevention and control, in-situ remediation mechanisms, reactive transport and numerical modeling, mining-related pollution source identification, and contaminated-site risk assessment. Research work integrates environmental engineering, hydrogeology, contaminant hydrogeochemistry, numerical simulation, and environmental management. Experienced in national and local research projects related to remediation-agent injection and reactive mixing in contaminated aquifers, antimony pollution source identification and flux assessment in mining areas, phosphogypsum stack environmental risk control, and heavy-metal migration and remediation in soil–groundwater–surface water systems. Skilled in field investigation, laboratory experiments, image-based analysis, numerical modeling, GIS mapping, and risk-based decision support. Published papers in journals including Journal of Hydrology, Journal of Contaminant Hydrology, and Physics of Fluids.
