A short introduction
I am currently a Ph.D. student at University of Illinois at Urbana-Champaign, advised by Heng Ji. Previously, I am undergraduate student studying at Tsinghua University, majoring in Computer Science and Technology and advised by Zhiyuan Liu.
My research interests primarily lie in the field of natural language processing, with a particular focus on tool learning and tool creation of large language models (LLMs), LLM-driven AI agents and its application in science, elicition and interpretability of LLM knowledge.
In 2023 summer, I worked with Sherry Wu on the impacts of external knowledge (e.g. from tools, retrieval, etc.) to parametric knowledge (paper). In previous research, I have investigated the tool creation ability of large language models (paper), and how the tool-use ability could be adapted to open-source models (paper). This 2024 spring, I have also investigated into how dialogue agent could understand human’s implicit intention (paper).
Before 2023, I have explored the concept of recycling outdated weights during the lifelong knowledge acquisition of LLMs, which was published in ACL 2023 findings (paper). Additionally, I have contributed to research on the mode connectivity of models’ various minima, which was presented at EMNLP 2022 (paper).
I am starting my Ph.D. from Fall 2024. If you are interested in my research or would like to collaborate, please feel free to reach out to me! (I am also actively seeking for internship opportunities in 2025 summer!)
Recent Research Focuses:
- Build LLM to understand human’s implicit intention in dialogue.
- Propose CREATOR to help automatic tool-creation.
- Adapt tool-using ability to open-source LLaMA models.
- Investigate the impact of external knowledge (e.g. from tools, retrieval, etc.) brought to LLMs.
