Hui Chen


I am a Research Fellow in the School of Computing in National University of Singapore, advised by Prof. Bryan Hooi. Previously, I worked at Nanyang Technological University and obtained my Ph.D. degree in Computer Science from Singapore University of Technology and Design and B.Eng. degree in Computer Science and Technology from Zhejiang University.

I'm currently working on LLM agents and large reasoning models. Feel free to contact me if you are interested in any discussions!
