Hi there. My research interest is about CONNECTION. I am studying Large Language Models (LLMs) and Multi-Agent System (MAS).

My current research interest:

1. Are LLM-based multi-agent systems sufficiently truthful, secure and efficient? How can we design valuable mechanisms to ensure this (both theoretically and empirically)?
2. How can we examine or reflect on LLMs (and multi-agent systems) from an anthropological perspective? Can we construct a culture for multi-agent systems? Furthermore, how can we evaluate the real value of highly metric-driven multi-agent systems for humans?
3. How can we attack the reasoning process of LLMs? How can we prove the inherent flaws (if they exist) in reasoning models? How can we distinguish different error modes in various LLMs? Furthermore, can competitive-level problems (including Olympiad Informatics problems) contribute to these studies?

Topics that may not be easy to get started in the short term, but I am still interested:

1. How can LLMs truly engage in meaningful role-playing or writing? These two tasks are similar in that they both reflect the linguistic state of a real, specific human.
2. How do language models model language? Can we understand the representation of (even multimodal) linguistic concepts in language models through probing models? Can modern and contemporary philosophy of language (continental or analytic) help reshape our understanding of these questions?

If you are also interested in these directions and would like to collaborate with me, please contact me immediately!

I love teaching and have been involved in the design of several courses as a TA. I am doing my best to reduce inequalities in course teaching and help everyone gain the same knowledge as much as possible.

I am very passionate about communicating with people. If you would like to discuss our shared research interests, or if you are my student (in SI 100B, SI 100+, or other courses) and want to chat for advice (though I am just getting started on many things myself), feel free to reach out anytime. You can also book a time with me through Calendly.

I like (non-fiction) writing and composing/mixing music.
