About me


I am a research assistant professor in the computer science department at the University of North Carolina at Charlotte. I am also a faculty member 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.

I am always looking for motivated and talented students to work with. If you are interested, please contact me via email. Research Assistantships are available to exceptional Ph.D. and Masters students.

I am seeking a tenure-track position beginning in Fall 2019/2020.
