Associate Professor, George Mason University
My research has been focused on mining spatial-temporal data with applications in transportation, epidemiology, social science, and urban computing. I'm a computer scientist who is passionate to work interdisciplinary.
I have a special interest in Geosimulation as a new paradigm to combine large-scale data generation with data mining to improve decision-making.
