👋 About Me

I am a Ph.D. student at LEVIR Group, Beihang University (BUAA), supervised by Prof. Zhenwei Shi (史振威，国家杰青) and Prof. Zhengxia Zou (邹征夏，国家优青海外). Previously, I received my bachelor’s degree from Beihang University in June 2021. My research interests lie in remote sensing image processing, deep learning, and multimodal learning.
