Hi! I am a final year Ph.D. candidate of computer science at Tsinghua University, supervised by Prof. Shu-Tao Xia (home). I received both my BSc and MSc of Information Security from Southwest Jiaotong University, supervised by Prof. Xiaohu Tang (home). I am also being supervised by Prof. Hongzhi Yin on recommender systems during my academic visit to The University of Queensland.
My research interests are in Federated Recommender Systems, Probabilistic Representation Learning, and their intersection with Graphs, Privacy, and Foundation Models in cross Edge/Cloud scenarios. I am currently focusing on the topic of Cost-Effective Vertical Federated Learning for Multi-Platform Collaborative Recommendation (CAI24') and am always open to collaborations or discussions on related problems or modeling tools. Welcome to email me :)
