I am a research scientist at the Department of Computer Science, University of California, Santa Barbara. I am a member of the Information Network Academic Research Center (INARC), and Network Science Collaborative Technology Alliance (NS-CTA).

My research spans the areas of Big data, databases and data management, with emphasis on graph database, graph query models and languages, and distributed/dynamic graph data. My broader interests include data quality, network science, security, web services management and information visualization.
