Biography

Hey! I am Wei Liu, currently a PhD candidate in Institute for Network Sciences and Cyberspace at Tsinghua University (THU), and fortunate to be advised by Prof. Yuanjie Li. Previously, I obtained my bachelor's degree from Beijing University of Posts and Telecommunications (BUPT).


My research interests fall in satellite network and security. The current research focuses on direct-to-cell satellite.
