I am a Research Fellow at National University of Singapore, working with Prof. Bingsheng He. I obtained my Ph.D. degree at Zhejiang University advised by Prof. Jiajun Bu. My research interests are mainly in machine leanring and data mining, particularly in graph neural networks, recommender systems, etc. I have served as the PC member for top-tier conferences including ICML, NeurIPS, ICLR, WWW, SIGKDD, AAAI, CVPR, ICCV, ECCV, etc; and the invited reviewer for prestigious journals including TKDE, TOIS, CSUR, etc. Feel free to send me an e-mail if you want to collaborate with me!
