Zhicong Sun (Zeeco)

Postdoctoral Fellow, NTU DISC Lab

I am currently a Postdoctoral Fellow at NTU Singapore, working with Prof. Bryan G. Pantoja-Rosero. I received my Ph.D. from PolyU, my M.Eng. from SUSTech, and my B.Eng. from HIT.

My research focuses on robotic perception, reasoning, action, and safety in dynamic and deformable environments, with a particular emphasis on applications in construction environments and emergency scenarios. My work asks what representation of space and time is sufficient for multiple robots to share when the built environment is changing both independently and through their actions.

I am always open to research collaborations, academic exchanges, and interesting ideas. Feel free to reach out via zhicong.sun@ntu.edu.sg
