Currently, I am a Ph.D student in the AML Lab at the School of Data Science, City University of Hong Kong. Before this, I earned my Master’s degree at CityU under the supervision of Prof. Zhao Xiangyu. I also obtained my Bachelor’s degree in Robotics Engineering from Southeast University, where Prof. Gan Yahui and Prof. Li Jun co-supervised me.

My research interest includes Recommender Systems, Information Retrieval & LLM. I have published several papers at the top international AI conferences with total Google Scholar citations.
