About Me

I am currently an AI researcher @ ByteDance. Previously, I received my Ph.D degree from School of Software of Tsinghua University, advised by Prof. MingSheng Long THUML.

My research interests cover Deep Learnning and Foundation Model. I am currently working on generic time series foundation models and agentic forecasting. My research aims to contribute to the advancement of intelligent systems capable of handling massive and complicated temporal data across domains.

For more information, please take a look at my Google Scholar and GitHub.
