About me

Hello! I’m Yuejin Xie (谢悦晋), an undergraduate student majoring in Electronic Engineering at Huazhong University of Science and Technology (HUST). I will join IIGROUP, Tsinghua Shenzhen International Graduate School as a Master’s student, advised by Prof. Yujiu Yang.

My research interests focus on LLM & Agent Safety, including tool-use safety, agent guardrails, and alignment.

You can find my work on GitHub and Google Scholar.
