Research Profile

PhD candidate in Information and Communication Engineering at Beijing Institute of Technology and CSC-sponsored visiting PhD researcher at the University of Auckland. My research focuses on remote sensing, image processing, self-supervised learning, and spatiotemporal analysis. I develop physics-aware and learning-based methods for reconstruction from noisy, sparse, and incomplete observations. My recent work spans UAV-based urban sensing, long-horizon time-series modelling, multimodal learning, and spatial reconstruction, with an emphasis on robust analysis of challenging remote sensing data. I have participated in 10+ national-level research projects, published 4 peer-reviewed SCI journal papers, and have additional first-author manuscripts under review in IEEE TGRS and IEEE TAES.
