My research interests are centered around large-scale data analysis, with a focus on online social networks (OSNs). Most of my work is measurement-driven and modeling based, using data mining and machine learning techniques. My research topics include graph analysis and modeling, studying human online behaviors (with an focus on financial markets), ranking/advertising on OSNs, and network traffic monitoring.
