Bio
I am a member of the Software Research group at the IBM Thomas J. Watson Research Center, in Hawthorne, New York, USA. My research interests include knowledge representation and reasoning, data management, information integration, programming and query languages for XML, and program analysis. My current work focuses on developing theories, algorithms and systems for 1) scaling reasoning over large and expressive description logics knowledge bases that tolerate inconsistencies and uncertainties and 2) efficiently aligning large ontologies. I am also investigating applications of Semantic Web technologies in a variety of domains ranging from life sciences to text analysis.
