Urban Computing and Spatio-temporal Data Mining

Mobility modelling foundations

Individual Mobility Behavior Modelling

This line modeled how people move through cities, moving from trajectory prediction to map matching, trajectory recovery, privacy-preserving prediction, and generative mobility simulation.

From individual behavior to citywide dynamics

Citywide Spatio-temporal Prediction

This line lifted mobility signals to city-scale dynamics, covering population estimation, crowd flow, traffic flow, network traffic, benchmarks, and universal spatio-temporal prediction.

Operational Urban Decision Systems

This line translates urban computing research into operational decision systems, from traffic signal control work to industry-scale logistics systems at Meituan. It connects spatio-temporal modelling, graph learning, dispatching, order pooling, and assignment optimization with real-world urban operations, including delivery-network work recognized as an INFORMS Edelman Award Finalist.
