I am currently pursuing a Ph.D. degree at the School of Geography and Planning, Sun Yat-sen University, China, under the supervision of Associate Professor Guangzhao Chen.

My research focuses on urban remote sensing and artificial intelligence, with particular emphasis on large-scale and fine-grained analysis of urban built environments. I am interested in developing AI-driven methods to support urban ecosystem analysis, urban planning, and spatial structure understanding through multi-source geospatial data.

Previously, I received my M.S. degree from the School of Geospatial Engineering and Science, Sun Yat-sen University, Zhuhai, under the supervision of Associate Professor Weijia Li. Before that, I obtained a B.S. degree in Geomatics Engineering from the Nanjing University of Posts and Telecommunications in 2022.
