Dr. Lei research interest is in Geographic Information Science, with a focus on algorithmic development, geospatial computational methods, network analysis, location theory, and web GIS.

Dr. Lei's research aims to develop efficient computational methods and models to solve new problems in transportation, urban planning, mobility and accessibility, water resources and sustainable development. He also has a keen interest in Remote Sensing as well as in advancing GIS technology itself in data structure and databases, computational geometry, web services, software engineering, and open-source technology.
