Research Interests

My research integrates GIS, complex networks/systems science, and spatial and statistical analyses to study the structure, function, patterns, and evolution of geospatial networks/systems, e.g., complex urban systems, transportation networks, and human social spatial contact networks. My primary interests are to investigate the relation between the persistent system level patterns and the individual based processes, and the effect of spatiality on the structure and function of the evolving complex spatial networks/systems.

One study on Texas urban system showed that the persistent macro level pattern of city size distributions can be better approximated by a spatially and temporally autocorrelated growth process of individual cities. Others addressed the structure and dynamics occurring on transportation networks. In addition, my recent projects applied GIS and spatial analysis to investigate the population vulnerability to hurricane wind and storm surge damages on the U.S. Gulf Coast over past five decades, and the spatial net migration patterns in the United States since 1950.
