NEWS I will be joining the School of Computer and Information Systems, Singapore Management University (SMU) in Fall 2024 as a tenure-track Assistant Professor. I am actively looking for highly motivated PhD students to join my group (2025 Spring/Fall). My group also welcomes research interns and visiting scholars (e.g., CSC Joint PhD Project), starting from Fall 2024. [Openings]

Yang Deng, 2023

I am currently a postdoctoral research fellow in NExT++, School of Computing, National University of Singapore, working with Prof. Tat-Seng Chua and Prof. See-Kiong Ng. Before that, 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
