My broad research interests are in analyzing, understanding, and making sense of big data generated from various complex networks in many contexts, including urban network analysis, large-scale network data sampling, measurement, online social behavior modeling. My recent research focuses on exploring the challenges in managing and analyzing big data from urban networks, with an ultimate goal of improving human life quality and designing smarter cities. I am a member of ACM and IEEE.Teaching and mentoring students is a very exciting and rewarding process for me, which has gradually enabled me to understand: Teaching is not just conveying knowledge to students, but a process to motivate and inspire students to learn and think creatively, independently, and critically.
