👋 Hello, I'm

Junjie Zhang

first-year Ph.D. student at Nanayang Technological University

I am a first-year Ph.D. student at Nanyang Technological University, advised by Prof. Dacheng Tao. I received my Master’s degree from Tsinghua University, advised by Prof. Xiu Li. Previously, I was fortunate to work closely with Dr. Chenjia Bai as an intern at Shanghai AI Lab.

My research interests lie in efficient decision-making systems with powerful generalization and self-evolution capabilities.
