Research Interests
My research interests lie mainly in the areas of remote sensing and geographical information science. The focus is placed on use of the-state-of-art Earth observation and mobile mapping systems to derive spatial and attribute information to support effective urban-suburban planning and environmental management activities; to extract geometric information of urban structures for developing theories and models of urban morphology; to detect land use and land cover changes to study spatiotemporal dynamics and consequences of urbanization as a major form of global changes.

My recent research projects are about the development of innovative algorithms/methods and software tools, including object-based image analysis for multi-scale thematic mapping of physical and built environments, airborne LiDAR point cloud processing for 3D urban modeling, laser scanning data processing for 3D infrastructure reconstruction, intelligent SAR image analysis for automated detection of oil spill, sea ice, and shoreline changes, advanced computer vision and machine learning for intelligent processing of remotely sensed data, as well as novel remote sensing applications in transportation, utility, agriculture, resources and disaster management.
