I lead the USTC Lab for Data Science. My research interests span information retrieval, data mining, and multi-media analytics. I have over 100 publications appeared in several top conferences such as SIGIR, WWW, and KDD, and journals including TKDE, TOIS, and TNNLS. My work on recommender systems has received the Best Paper Award Honourable Mention in SIGIR (2021, 2016) and WWW (2018). Moreover, I have served as the Associate Editor for journals including ACM TOIS, IEEE TBD, etc., and (senior) PC member for conferences including SIGIR, WWW, KDD, MM, etc.
