Postdoctoral Research Fellow at NUS

NExT++ Research Center
School of Computing
National University of Singapore


I am a Postdoctoral Research Fellow at NExT++, National University of Singapore (NUS), working with Prof. Tat-Seng Chua. I received my Ph.D. from NUS in 2026, supervised by Prof. Tat-Seng Chua and mentored by Wenjie Wang. Prior to that, I obtained my Master’s degree from Shandong University in 2022, supervised by Prof. Liqiang Nie and mentored by Prof. Meng Liu. I have also interned at ByteDance Seed, working with Dr. Lu Jiang and Dr. Feng Cheng.

My research interests lie in Visual Content Generation, Multimodal Information Retrieval, and Multimodal Large Language Models.

Openings: We welcome motivated Ph.D., M.S., and undergraduate students to join our group and work with Prof. Tat-Seng Chua and myself. Opportunities are open via CSC scholarships, research assistantships, visiting positions, and remote internships. If you are interested, please reach out at leigangqu@gmail.com with your CV.
