I am a first-year Ph.D. student at the Center for Secure Information Systems (CSIS), George Mason University, advised by Dr. Kun Sun . My research focuses on systems security, including confidential computing, trusted execution environments (TEEs), and software-hardware co-design. Previously, I also worked on cryptographic protocols.
Before joining GMU, I received an M.S. in Network and Information Security from Huazhong University of Science and Technology under Dr. Jie Wang, and a B.S. in Cyberspace Security from the University of International Relations.
