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.
