Research Interests

Dr. Xu’s primary research focuses on applying GIS, spatial and statistical analyses to study human population dynamics at different spatial scales in the United States. These include the growth and decline of population of cities, population migration across difference places, neighborhood effects on people, etc. He is also interested in approaching these dynamics by using the network/system methods, to study how places and people are interconnected to form the structures and patterns of the geospatial systems, and how the systems evolve over time.

His ongoing projects include studies on neighborhood effects on birth outcome and violence incidents in City of Milwaukee, areal interpolation of population on census data, epidemic diffusion along social contact networks, and effects of hurricane damages on populations along U.S. Gulf and East coasts.
