    Research
    I joined PKU Visualization and Visual Analytics Group in 2009. My major research interest is transportation visual analytics. I started from studying the micro behaviors of vehicles and pedestrians at a road intersection with laser scanner dataset. It ended up with an exploratory trajectory visual analysis system called TripVista. Later I began to study macro patterns of city scale transportation data, including taxi GPS data and transportation cell data. I tried to visualize the traffic jam propagation patterns in Beijing with taxi GPS data, and the traffic network flow patterns in Nanjing with transportation cell data. I hope one day my research can help improve the urban transportation system.
