I’m pursuing my doctoral degree in Computer Science in , IIOT Lab, at Shanghai Jiao Tong University, where I have the honor to be supervised by Prof. Luoyi Fu and Prof. Xinbing Wang.

My research interests include natural language processing, knowledge graphs and data mining. Specifically, I am devoted to research of large language models and temporal knowledge graph.

What’s more, welcome to my technical blog OmegaXYZ and 中文博客.
