My research interests span across information visualization, network visual analysis, and interactions. I am especially interested in the design of scalable techniques or systems that enable interactive exploration of large or complex datasets. In the past, I have worked with parallel coordinates, multiple coordinated views, multidimensional projection, and graph drawing.
