Hai Ci

Currently, I am a Research Fellow at National University of Singapore. I received my Ph.D. from School of Computer Science at Peking University (PKU) advised by Professor Yizhou Wang.

My research interests lie in computer vision and multi-agent learning, with a particular focus on perceiving and understanding human behaviors from static images or mobile robots.
