Personal Details : 
My research focuses on remote sensing of coastal wetlands and wetland ecological monitoring, with particular emphasis on long-term dynamic changes in coastal ecosystems such as salt marshes and tidal flats. I aim to develop interpretable, transferable, and applicable intelligent remote sensing methods to support coastal wetland conservation, restoration, and ecosystem management. My research interests include: (1) long-term time-series remote sensing and intelligent mapping of coastal wetlands, (2) remote sensing monitoring of coastal ecosystem evolution, (3) monitoring, management, and secondary invasion early warning of Spartina alterniflora, and (4) large-scale intelligent mapping methods driven by multi-source remote sensing data. My research has been published in journals including ISPRS Journal of Photogrammetry and Remote Sensing, International Journal of Applied Earth Observation and Geoinformation, Agricultural Systems, and Ecological Indicators. I have also been granted two Chinese invention patents.
