Hi, I am Jiaxuan Zou (邹嘉轩).

I am currently an undergraduate student at the School of Mathematics and Statistics, Xi’an Jiaotong University, and a research intern at the Gaoling School of Artificial Intelligence (Renmin University of China), advised by Prof. Yong Liu.

I work on mechanistic understanding and interpretability of deep learning. My approach is phenomenon-driven: start from empirical behaviors, then build first-principles mechanisms that explain why a model works (or fails) and where certain behaviors come from.

Research Interests

Mechanistic interpretability of LLMs
Deep learning theory & optimization
