My research is generally in the areas of web-scale information management, distributed data-intensive systems, and social computing. Fundamentally, my overall research goal is to develop algorithms and systems to enable efficient and trustworthy information sharing and knowledge discovery over dynamic, heterogeneous, and massive-scale networked information systems.Teaching (full list)
