Lingzhi Yuan

Hi! I'm a Computer Science Ph.D. student at the University of Maryland, College Park, advised by Furong Huang.

My research spans three directions.

  • Trustworthy Machine Learning. Aligning today's models and the agent systems they drive with human ethics, and making them run reliably in real-world environments.
  • Self-evolving Agents. Designing mechanisms that let agents accumulate experience at deployment time, completing tasks better and at lower cost.
  • Multi-agent Systems. Discovering collaboration patterns that let multiple relatively weak models jointly solve tasks a single strong model struggles with.

I obtained my B.Eng at Zhejiang University, majoring in Automation. I was also a research assistant at the Secure Learning Lab, University of Chicago, advised by Bo Li.

See my resume for more detail, or find the non-research side of me here 🧩.

Feel free to get in touch if any of this sounds interesting to you.

About Me

Here are things other than scientific research.

Personal interests

I love music 🎶, especially indie music of all kinds — rock, R&B, and so on. I also play keyboard and piano 🎹, and I used to play keyboard in bands on campus.

I won't miss a live performance by my favorite musicians. I believe a live show is the best way to enjoy music. In my free time I also watch a lot of films and series.

Selected favorite albums

Notes from my undergraduate studies

Taking notes on Notion was one of my habits at ZJU. My notes (in Chinese) live on this Notion page.

My video channel

I sometimes upload videos about music and everyday life to my bilibili account.
