Biography

I am a tenure-track Assistant Professor in School of Computing and Information Systems, Singapore Management University. Before that, I was a Postdoctoral Research Fellow in National University of Singapore (NUS), where I was a member of NExT++ Research Center, supervised by Prof. Chua Tat-Seng. I was also under National Cybersecurity R&D Lab, where I worked with Prof. Chang Ee-Chien and Prof. Liang Zhenkai. I got my PhD from NUS in 2022, supervised by Prof. Chua Tat-Seng.

My research focuses on the emerging and practical problem of multimodal event forecasting, which aims to understand multimodal information and make forecasting in various domains, such as international politics, macro economy, finance, cyber threats, fashion trend, etc. I am also working on computational fashion, including personalized mix-and-match, fashion outfit generation, fashion report generation, etc. In addition, I study a specialized branch of recommender system, i.e., bundle recommendation, including multimodal bundle construction and recommendation. In summary, I am interested in investigating computational (e.g., data mining, information retrieval, and multimedia) approaches to solve realworld problems. I am enthusiatic in discovering, formulating, and solving new and crucial problems, which have been not or rarely touched by the current academic and industrial community.
Here are some talk slides that introduce my works in these directions:
  [Bundle Recommendation and Generation] Aug. 2025, present at a workshop on generative recommendation. [slides]
  [LLM for Cyber Threat Intelligence (CTI) Analysis] Sep. 2025, present at SMU-SCIS MITB AI translational seminar. [slides]
  [AI That Sees the Future: Multimodal LLMs for Open-World Forecasting] Sep. 2025, present at SMU-SCIS research cluster seminar. [slides]
