Center for Visual and Decision Informatics

I am an Associate Professor in the School of Computing and Informatics at the University of Louisiana at Lafayette and a member of the Informatics Program. I received my Ph.D. degree in Computer Science from the University of Texas at Dallas in 2012. My general research areas are complex systems and data/graph analytics. My ongoing research involves network topology mapping, modeling and analysis for Internet security, reliability and efficiency as well as large-scale graph data sampling and summarization for real-world complex system visualization and analysis.
