Dongway Sun | Xi'an Jiaotong University

About Me

Welcome! I am a Ph.D. candidate in Computer Science and Technology at Xi’an Jiaotong University, focusing on advancing artificial intelligence and computer vision. My research centers on Remote Sensing and Medical Image Processing combined with Multimodal Machine Learning. I develop deep learning approaches for change detection, image captioning, and cross-modal understanding. I hold a Master’s degree in Computational Mathematics from Northwestern Polytechnical University and previously worked as an Associate Research Fellow for over two years, specializing in designing and deploying AI algorithms for real-world applications.
