Research

My research interests lie in computer system security. In particular, my research lies in operating systems, program analysis, and compiler transformation & optimization. I have been working in the following directions:

1. Hardware-assisted execution environment, particularly for Linux eBPF.
2. Compiler-based code optimization and obfuscation.
3. Binary analysis and binary code similarity detection.

Skills

• Compiler: Proficient in LLVM compiler architecture, front-end/middle-end/back-end programming, program analysis, code transformation, and profile-guided optimization.
• Kernel: Experienced in kernel bypassing, eBPF, Linux kernel analysis, operating system development, and kernel debugging.
• Reverse Engineering: Skilled in binary code diffing and rewriting techniques.
• Others: Familiar with Intel/ARM hardware characteristics, Trusted Execution Environment principles and design, and fuzz testing.
• Programming Languages: C / C++ / Assembly / Python / Shell / Java / JavaScript
