Designed and implemented a compressed database system that uses compression techniques to improve database query performance. This is the first system that integrates compression into all aspects of database systems. Another work is a novel compression method for low-power mobile devices such as PDAs and cell phones, which achieves both better compression and faster decompression than existing methods.
Research Intern, AT\&T Laboratories Aug 1999 - Sep 2000
Designed and implemented algorithms and data structures to give quick and accurate estimation of the result size of queries on text or XML data. This can be used in web search engines to allow user to quickly refine queries based on the estimate.
