About me


I am a Research Associate at the Charlotte Visualization Center. My main research interests are Virtual Environment, 3D User Interface, Interaction Technique, Human Computer Interaction, Visual Analytics and interactive 3D/2D visualization . I received a Ph.D. in computer science from the University of North Carolina at Charlotte in 2013.
