I am a Senior Technical Staff Member (STSM) working in the Database Research Group at IBM T.J. Watson Research Center at Hawthorne, New York. My interests are in new research directions in data management and its applications. In particular I am interested in scalable database processing, clustering and indexing techniques, query processing and optimizations, compression, information integration, access control and privacy protection and data management in new hardware.

Prior to joining IBM Research, I was associated with the Database Technology Group (DBT) at IBM Toronto Labs, Canada and the Advanced Numerical Research and Analysis Group (ANURAG) of the Ministry of Defence, Government of India, India.

Over the last several years I have been involved with the Multi Dimensional Clustering (MDC) physical layout scheme for relational tables, Scan Sharing for relational tables, Index Compression and RDF Store for DB2 LUW projects. These have been incorporated in various DB2 Linux, Unix and Windows (LUW) releases in collaboration with IBM Toronto Labs. Before that I was involved with the DB2 Parallel Edition (DB2 PE) project and the industries first ever TPCD benchmark.

I am also involved in exploratory projects in the areas of data management on new hardware, privacy preserving data federation and its applications, database access control and schemaless relational storage schemes.

My work in the MDC project has been recognised with an IBM Outstanding Innovation Award and two Supplemental Outstanding Innovation Awards by the company. I was also nominated to the Corporate Technical Recognition Event (CTRE) 2006 for the same. My work on Scan Sharing for relational tables and Index Compression has been recognized with a Eminence and Excellence Award and also an Outstanding Technical Achievement Award. My work is also part of four Research Division Accomplishments, one Outstanding Research Division Accomplishment and one Extraordinary Research Division Accomplishment. Apart from this I have also received Patent Plateau and other lesser awards for my other contributions.

I am currently serving as a Conference Officer for ACM SIGMOD 2013, on the Program Committee of IEEE Big Data 2013 and as a reviewer for ACM TODS and TKDE .

Recently I have been inducted as a Member of the IBM Academy of Technology. I have also been elected as a IEEE Senior Member
