Sriram Padmanabhan
I am a Research Staff Member
and manager of the Parallel Databases group. Our group is interested
in new research directions in data management and its applications.
Our research topics include
- High-end, scalable
database processing
- New clustering
and indexing techniques
- New algorithms
for query processing and optimization
- XML based data
management and middleware for data integration
- New search and
query paradigms, similarity, nearest-neighbor, etc.
- Multi-Dimensional
Data management issues
- Distributed
and pervasive support
- E-Commerce Applications
and performance issues
I am also the Watson chair for the Data Management PIC.
