Gangle Sun

Gangle Sun received the B.E. degree in communication engineering from Tianjin University, Tianjin, China, in 2019, and the Ph.D. degree in information and communication engineering from Southeast University, Nanjing, China, in 2025. From 2022 to 2023, he conducted visiting research with the Department of Information Technology and Electrical Engineering, ETH Zurich, Zurich, Switzerland. Since 2025, he has been with the Faculty of the College of Information Science and Engineering, Hohai University.

His research interests focus on compressive sensing theory, optimization theory, artificial intelligence, and their applications in massive connectivity, cell-free communications, and satellite communications. He has published 20+ papers in leading SCI journals and EI-indexed conferences, and has long been involved in the National Key R&D Program of China, NSFC General Programs, and multiple university–industry collaboration projects. He also serves as a reviewer for journals including IEEE Transactions on Wireless Communications, IEEE Transactions on Communications, IEEE Transactions on Cognitive Communications and Networking, and IEEE Transactions on Vehicular Technology.

Undergraduate and graduate students interested in related areas are welcome to join our research projects.
