Hi, I’m Hung-Chun CHIU, a M.Phil. student at Hong Kong University of Science and Technology (HKUST), advised by Prof. Charles Zhang. Before that, I obtained my Bachelor’s and Master’s degrees from Tsinghua University.
My research interests lie in software security, with a focus on greybox fuzzing, program analysis, and LLM agent security. My recent work explores secure and reliable LLM agents, including defenses against prompt injection, the security of LLM-generated code, and the integration of agent technologies with fuzzing to improve automated vulnerability discovery and software security.
