Extensive research and development experience in the data management area. Work has been published in top conferences such as SIGMOD, VLDB, ICDE, etc.* Transactional key-value stores. Built design tools for balancing performance and consistency in key-value stores in a principled manner; built physical design tools to automatically suggest indexing and data layout options for best throughput.* Database on storage class memory. While visiting IBM Research's SCM group, I worked with a team to design and prototype a database systems that best utilize the non-volatility of storage class memory. We designed novel data structures and a series of transaction processing and recovery algorithms. We prototyped a functional system for demonstration.* Information extraction and text analytics. While visiting IBM Research's SystemT project, I built a provenance-based automatic refinement engine for information extraction rules. This tool takes labeled extracted results and suggest changes to rules to best improve the precision and recall of the extraction process.* Making it easier to perform analytics on databases. Designed novel query interface for users to formulate powerful SQL queries directly on a spreadsheet through direct-manipulation of data.* Helping users navigate a large data set through data clustering. Users can drill-down and filter data easily through the clustering structure I built.* Spatial databases and mobile computing. Designed caching algorithms for mobile peer-to-peer networks; designed and implemented a system for supporting multi-dimensional queries in a peer-to-peer system. Hands-on experience with spatial data structures such as R-tree.
