I am a research staff member working for the GeoVISTA Center, Department of Geography at Pennsylvania State University. My scientific pursuit has two foci: (1) developing methods for data analysis in and knowledge construction from spatial, temporal, and multivariate data; and (2) on applying the methods to address practical problems in sub-disciplines of geography including (but not limited to) public health, environment, natural hazard, economic, and so on. My research adopts multidisciplinary approaches ranging from visualization, cartography, to statistics, computation, data mining and artificial intellegence.
Prior to joining Penn State, I worked in industry, with primary focuses on software development, information technology, and enterprise information system (e.g., ERP). Later, I found scientific research is more interesting, and started to pursue a Ph.D. of Geography at Penn State, focusing on Geovisualization and GIS.
