Research Interest

My main research interests include unstructured data analytics, multimedia information retrieval, recommendation and conversation systems, and the emerging applications in e-commerce and fintech. To further research emerging topics in these areas, I set up the Lab for Media Search (LMS) at SoC and conduct regular seminars. Since 2010, I have served as the co-Director of NExT Center, a joint research center between NUS and Tsinghua University on Extreme Search. the co-Director of NExT Center, a joint research center between NUS and Tsinghua University on Extreme Search. For my current list of research topics, please refer to https://nextcenter.org/research.
