I have launched my research group webpage today: City Science Group. The group has different research themes including urban transportation modelling & analytics, understanding human mobility patterns in cities, urban big data, multi-modal urban transportation planning and operations, bicycle and pedestrian innovations, and urban freight and logistics.
There are currently a few PhD positions available at my group. Qualifications include BS/MS in Science, Engineering, or Mathematics. Applicants with a Master's degree with one or more of the following backgrounds are preferred: transportation network/traffic modelling, operations research (optimization), complex networks, and online data visualization.
