Hi, I am Zhe Yu (俞哲) from Hangzhou, China. I am a Research Intern at the Binjiang Institute of Zhejiang University (IFRC Lab), where I work on trustworthy language models with Dr. Meng Han and Dr. Wenpeng Xing. I am currently pursuing my B.Eng. in Artificial Intelligence at the Communication University of Zhejiang (CUZ), supervised by Dr. Hao Zeng. During my undergraduate studies, I also spent time as a Visiting Student at Westlake University (supervised by Dr. Ziyang Zhang) and the University of Malaya.
📢 Seeking Opportunities: I am actively looking for Research Assistant (RA) positions (on-site or remote) and seeking Fall 2027 PhD opportunities. Please feel free to drop me an email if you are interested!

My research centers on trustworthy language models across three interconnected threads. First, I study the internal mechanisms of knowledge grounding — how parametric memory and retrieved evidence interact during generation, and how to detect failures like hallucinations, memory hijacking, and compositional reasoning collapse through white-box monitoring and mechanistic analysis. Second, I work on representation–action dissociation in reasoning and agentic systems — probing when and why models encode conflict information internally yet fail to route it into downstream decisions. Third, I explore verifiable model ownership and decentralized trust — combining fingerprinting, blockchain, and zero-knowledge proofs to build scalable, privacy-preserving attribution and deployment frameworks.

- Visiting Student, Optical Laboratory, supervised by Dr. Ziyang Zhang. Worked on dual all-fiber interferometer systems for orthogonal salinity/temperature detection (published in Optics Communications). This early cross-disciplinary research grounded my experimental rigor and shaped my approach to extracting and interpreting internal signals — a methodology central to my current work on LLM mechanistic interpretability and white-box auditing.
