Ai Group dedicates its effort towards establishing a comprehensive, spatially-enabled transportation infrastructure and asset data platform to better manage, support and sustain the current and future transportation infrastructure system, via employing imagery, mobile LiDAR, and GPS/GIS technologies, and developing computer vision, machine learning, and spatial analysis methods.
Ai Group will continuously look for talented undergraduate, graduate and postdoctoral researchers. Research assistantship and other sponsorship will be provided for qualified candidates. For undergraduate research assistantship, please check on the UMass Amherst Student Job Board, where openings in Ai Group will be posted periodically. For graduate research assistantship, please refer to the Graduate School Admission Office for general requirements, and email Dr. Chengbo Ai with your recent CV and names of your references. For postdoctoral researchers, please directly contact Dr. Chengbo Ai to further discuss your research interests and plan.
