Han Bao

Incoming Ph.D. Student in Computer Science & Engineering University of Notre Dame

I study reliable and aligned LLM agents, with an emphasis on failure diagnosis, deployment-time risks, and trustworthy evaluation.

About Me

I am an incoming Ph.D. student at the University of Notre Dame, joining in Fall 2026 under the supervision of Prof. Fanny Ye. Prior to that, I completed my undergraduate studies in Cyber Science and Engineering at Sichuan University.

During my visiting studies, I was mentored by Prof. Xiangliang Zhang and senior researcher Yue Huang, whose guidance shaped my research interests in trustworthy AI and foundation models. I continue to collaborate closely with Zheyuan Zhang.

My research focuses on trustworthy AI for LLM agents, with an emphasis on reliability, alignment, and evaluation under realistic training and deployment conditions.

Research Interests

  • Reliable LLM Agents and Failure Diagnosis

    I study how LLM agents fail across multi-turn interaction, input faults, and cooperative settings, how those failures can be diagnosed, and how execution experience can make agent harnesses more adaptive.

    Selected works MemoHarness arXiv'26 Drift-Bench ICML'26 IntraAI WWW'26 Demo
  • Alignment under Training and Deployment Shifts

    I investigate how alignment risks emerge as models acquire new capabilities or move into constrained deployment environments, together with guardian and advisor mechanisms for safer behavior.

    Selected works Capability-Oriented Training Induced Alignment Risk ICML'26 Guardian-as-an-Advisor ACL'26 Findings AI Alignment Breaks at the Edge Position Paper
  • Evaluation for Trustworthy Foundation Models

    I develop benchmarks and evaluation protocols that test whether generative, vision-language, and domain-specific foundation models remain reliable in realistic use cases.
