Biography
Dr. Zhang obtained his Ph.D. from the Department of Architecture and Civil Engineering, City University of Hong Kong. Prior to this, he received his B.Eng. and M.Eng. degrees from the School of Transportation Science and Engineering at Beihang University. His primary research interests lie in the domain of intelligent evacuation and crowd dynamics. He is particularly focused on developing intelligent evacuation guidance systems for large-scale facilities, leveraging agent-based simulation, machine learning, and large language models. He aims to solve complex decision-making problems in emergency scenarios to enhance safety and efficiency in transportation hubs and high-density buildings.
