My research interests mainly focus upon both the theoretical development of GIScience and the applications of GIS technologies in urban and regional analysis. I consider myself as a member of the still-growing research community, GIScientists. Currently I am actively involved in exploring the adoption of GeoComputational methods in geographic studies, which I believe has the potential to revolutionize both quantitative and qualitative studies in geography. In summary, my main research interests include:
· Spatial Data Mining and Knowledge Discovery: Simply put, the advance of IT, wide accessibility of computers, and accumulation of massive data provide the basis to ‘Let data speak for themselves’.
· Geovisualization and Information Visualization (Information Spatialization): Innovative visualization methods for facilitating thinking and problem solving in geographic domain. This goes beyond the traditional domain of cartography.
· Space-Time Dynamics: Current GISs are built upon a visually-oriented cartographic representational paradigm and it’s very difficult for them to handle temporal information effectively. A smart GIS should be the one that could offer reasoning (especial temporal reasoning) capabilities on its data and provide the related information required by users at the right time.
· GIS for Urban & Regional Analysis: GISs, as geographic analytical toolbox, have been used in various fields of urban and regional studies. This is an area calls for most the integration of GIS and spatial analysis methods. My area of research mainly focuses on urban commuting, public transit, crime & public safety, public health, economic development, groundwater pollutions.
