I am an Associate Professor in the Department of Computer Science at the University of Alabama in Huntsville. I investigate how the marriage of interactive visualization with various display technologies can enhance people's ability to analyze and understand the escalating quantity of data. My research focuses on the design and development of visual analysis techniques and tools that leverage mixed displays including mobile devices and tiled display walls.

I have also designed and developed interactive visualizations that facilitate greater insights into complex data in a broad range of application domains, including intelligence analysis, cyber security, crisis management and social network services, pavement evaluation, and computational chemistry.

I received my PhD degree in Computer Science from Virginia Tech, and I have also worked at POSTECH, National Instruments, and Tableau Software.
