大模型智能体LLM Agents深度研究Deep Research医学人工智能Medical AIAI + 教育AI for Education

你好!我是李泽坤,目前在清华大学智能产业研究院(AIR)读研究生,接下来将在清华继续攻读博士学位。

我做的是真正能干活的大模型智能体——会自己搜索、阅读、推理;并且希望把它们用在最需要的地方:医学和教育。

  • 🩺 医学深度研究。 我主导研发了 TIMO:一组轻量级智能体模型(4B / 27B,即将开源),能够上网检索、阅读证据并推理,回答困难的医学问题。
  • 🎓 教育智能体。 用多智能体系统,从学生”做了什么”而不只是”说了什么”来评估批判性思维,并探索大模型智能体如何重塑在线教与学。

Hi! I’m Zekun (泽坤). I’m a graduate student at the Institute for AI Industry Research (AIR), Tsinghua University, and will continue my Ph.D. journey at Tsinghua.

I build LLM agents that actually do the work — searching, reading and reasoning — and I care about putting them where it matters, in medicine and education.

  • 🩺 Medical deep research. I lead TIMO, a family of small agentic models (4B / 27B, open-source release coming soon) that browse the web and reason over evidence to answer hard medical questions.
  • 🎓 Agents for education. Multi-agent systems that assess critical thinking from what students do, not only what they say, and that reimagine how people teach and learn online.
