M.S. in Computer Science, University of Chicago
B.A. in Philosophy, East China Normal University
I'm an M.S. student in Computer Science at the University of Chicago. I started out in philosophy at East China Normal University and moved into machine learning through research and industry work on large language models. Philosophy gave me the questions; engineering gave me ways to test them.
I study how LLMs reason, and where they only pattern-match, how AI is changing the way people write, and how to make what models produce auditable. On the engineering side, I post-train multimodal LLMs with SFT and RL (GRPO) and build research agents that cite their sources and check their own citations.
Do LLMs reason, or do they only sound like they do?

AAAI 2026 Bridge Program on Logical and Symbolic Reasoning in Language ModelsAcross 11,000 syllogisms in all 44 classical forms, five LLMs find the same forms hard (mean pairwise r = 0.886). Every model accepts valid conclusions far more reliably than it rejects invalid ones (a 26–35 point gap), and accuracy rises when the middle term is the grammatical subject.
