Research Interests

I am a broadly trained geographer with substantive interests in remote sensing, geographic information science, spatial analysis, and their applications in urban environments. Specially, my research focuses on two aspects: 1) remote sensing image analysis and applications, especially for urban impervious surface and population estimation, as well as urban growth modeling, and 2) spatial analysis and modeling, and their applications in housing market analysis, public health, and transportation studies.

One emphasis of my research is to develop innovative methods for better extracting urban biophysical and socio-economic information, and applying the derived information for planning and management of urban and natural environments. Especially, my research in the urban remote sensing field includes 1) urban imperviousness estimation, in particular using the spectral mixture analysis method, 2) small area population interpolation and estimation using high-resolution remote sensing and GIS dataset, and 3) urban growth monitoring and modeling using spatial modeling techniques. In addition to remote sensing and urban analysis, my other research area involves GIS and spatial modeling (spatial optimization, spatial statistics, etc.) and their applications in housing market analysis, public health, and transportation studies.
