Liangzhe Han is a Postdoctoral Researcher whose research lies at the intersection of Artificial Intelligence and Urban Computing. He received his Ph.D. degree in Computer Science from Beihang University in June 2025. He also obtained his B.Eng. degree from the School of Software, Beihang University. His research focuses on spatio-temporal data mining, human mobility modeling, intelligent transportation systems, graph representation learning, and foundation models for urban intelligence. His goal is to understand large-scale collective human behaviors from urban data and develop intelligent analytical frameworks for smart city governance and decision-making. He participated in several major national and industrial research projects, including the National Natural Science Foundation of China (NSFC) Regional Joint Fund Program, the Guangxi Innovation-Driven Development Program, and industry-sponsored collaborative projects. His representative contributions include dynamic graph learning for traffic speed forecasting, origin-destination demand prediction, and generic crowd flow modeling. Beyond academic research, he has been actively involved in developing large-scale mobility foundation models based on real-world mobile signaling data. He contributed to the development of the Jiutian Chuanliu Mobility Foundation Model, which supports a wide range of urban intelligence applications, including urban governance, transportation planning, and business intelligence. Related achievements have received multiple recognitions from academia and industry, including the ITU AI Award and the Top Ten Leading Scientific and Technological Achievements Award at the China International Big Data Industry Expo. To date, he has published 31 papers, including 7 CCF-A level journals/conference papers, with more than 1171 citations on Google Scholar. His work has received several research awards, including the Special Award of the China Highway Society Science and Technology Award.
