Biography

I am an Associate Professor at Institute of Computing Technology (ICT), Chinese Academy of Sciences (CAS), where I obtained my Ph.D. in 2021. I am more than lucky to be co-supervised by Prof. Qing He and Prof. Fuzhen Zhuang during my doctoral studies. Before coming to ICT, I got my B.Eng. degree in Computer Science and Technology from Bejing Institute of Technology. From Sept. 2019 to Sept. 2020, I visited the UCL NLP Lab at University College London (UCL), where I worked with Prof. Sebastian Riedel and Dr. Pasquale Minervini.
My research interests lie in data mining and machine learning, with a special focus on the representation and application of knowledge graphs. Currently, I am working on the following topics:

• Large Language Model (LLM), LLM Hallucination, LLM Reasoning, Retrieval-augmented Generation (RAG)
• Knowledge Graph (KG), KG Construction/Embedding/Completion, KG for NLP Tasks
• Recommendation System (RS), LLM-based RS, KG for RS/Information Retrieval (IR), Fairness-aware RS
• Spatio-temporal Data Mining, Multivariate Time Series Forecasting, Traffic Forecasting

Recruiting: I have several 1-2 openings for visiting (bachelor, master, or Ph.D.) students on Knowledge Graph, Recommendation System, or other Data Ming and NLP topics. Both remote and onsite visiting are welcome. Ping me if interested!
