Research Area: Web Information Management |
Profile
Currently, my main research interests are scalable social information management, information discovery and exploration on social content sites, information extraction management and database usability.
I joined the Community Systems Group at Yahoo! Research New York, in July 2007. I have been mainly involved in two projects: Purple SOX and Royal Jelly.
I graduated from the Database Group at the University of Michigan, Ann Arbor, with a Ph.D. degree in Computer Science and Engineering. My advisor is Prof. H. V. Jagadish.
