My research interests are in network science, data science, networking, and networked/computing systems. My recent focus is on

Efficient algorithms and computational tools for graph mining and network analysis,

Modeling, analysis, and control of epidemic/information spreading, and

Machine learning for mobile and IoT applications.

I am also interested in big data analytics acceleration, and modeling, analysis, and optimization of large-scale networked systems.
