About

I am a PhD student in Computer Science at Arizona State University, advised by Dr. Ruoyu Wang. I received my bachelor's degree in Cybersecurity from Sichuan University in 2023. I am also a member of the Shellphish CTF team.

My research interests include decompilation, binary analysis, LLM for security, and vulnerability discovery.

Projects

Oxidizer

Dec 2023 - Present

A Rust-oriented decompiler. Conducted an empirical study of Rust-specific decompilation challenges and designed a novel Rust decompilation pipeline with multiple techniques to address these challenges.

Pluto

Jun 2021 - Jan 2024

An LLVM-based obfuscator that converts source code into functionally equivalent but much more complicated form at compile-time. Features include string encryption, control flow flattening, bogus control flow, MBA obfuscation, and indirect call obfuscation.
