About

I am a Ph.D. student in Computer Science and Engineering at The Ohio State University, where I am fortunate to be advised by Prof. Ping Zhang. Previously, I received my Master's degree in Computer Technology from the University of Science and Technology of China (USTC), advised by Prof. Qi Song.

My research centers on temporal data analysis and its real-world applications — spanning time series forecasting, graph-structured learning, and AI for scientific discovery (e.g., battery modeling). Recently, I have been exploring how LLM-driven agents can automate and advance the modeling of temporal data.
