Biography

Dr. Widener's research interests include experimental systems, I/O and storage software for large-data environments, middleware, and the generation and use of metadata.  Dr. Widener received his Ph.D. in Computer Science from the Georgia Institute of Technology in 2005, and before coming to CCI was Research Assistant Professor in the Department of Computer Science at the University of New Mexico.  Prior to beginning his Ph.D. studies, he was employed as a software developer by several companies which no longer exist.  He also holds a Master of Computer Science degree from the University of Virginia (1992), and a Bachelor of Science in Computer Science from James Madison University (1990).
