Online Social network data analysis and information diffusion research. Analyze the large amount of data from micro-blog (a china version twitter) based on Hadoop, Hama and Spark, major on relationship network and the information cascades dynamics. And also develop networks from the data and capture the critical network properties by distributed computing, to find how the structure of network affects the information dynamically spread on it. The research includes: (1)User influence measurement, (2)Burst event detection and prediction, (3)Information cascades modeling, (4)Information diffusion prediction.

Human mobility patterns and anomaly detection. Based on large scale anonymous Los Angeles city mobile phone users data set, which contains imprecise geographic information, analyzed the human mobility pattern under different scales, propose several anomaly detection measurements, and found out that the urban area people have regular weekly mobility pattern under stable circumstances, the pattern is highly predictable.
