NEWS I am actively looking for highly motivated PhD students (2025 Fall). I have several student RA positions avaiable (standard monthly stipend of 2700 SGD). My group also welcomes visiting scholars (e.g., CSC Project). Feel free to reach out to me as [Openings].
I am currently a tenure-track Assistant Professor in School of Computing and Information Systems, Singapore Management University. Before that, I was a postdoctoral research fellow in NExT++, School of Computing, National University of Singapore, working with Prof. Tat-Seng Chua and Prof. See-Kiong Ng. I received my Ph.D degree at The Chinese University of Hong Kong, supervised by Prof. Wai Lam.
My research mainly lies in Natural Language Processing (NLP) and Information Retrieval (IR) – with special focus on
