I am a second-year PhD student at The Ohio State University (OSU), advised by Prof. Huan Sun and working closely with Prof. Yu Su. Previously, I obtained my Master's and Bachelor's degrees from University of Science and Technology of China (USTC), advised by Prof. Enhong Chen.

I am broadly interested in NLP and related fields. My current research focuses on language agents, with the goal of building trustworthy AI agents that can reliably assist humans by automating complex or tedious tasks. Recently, my work has explored agent safety and security (MisAct, AutoElicit, RedTeamCUA), model-based planning for web agents (WebDreamer) and evaluation of agents on long-horizon web search tasks (Mind2Web 2).

Feel free to reach out if you are interested in my research or potential collaborations.
