The primary goal of my research is to develop fundamental concepts and new principles of data mining, design intelligent algorithms and build scalable systems.  Our current work has concentrated on three key areas: Modeling, managing, and mining large-scale, heterogeneous graphs; Structural and statistical analysis of texts and their applications such as information extraction, question answering, and information trustworthiness; Intelligent solutions to cross-domain problems in bioinformatics, business intelligence, computer security, computer systems, and social science.

Research Areas: Data mining, data management and machine learning
