Professional Work Experience

  • Intern in Windows Live Search at Microsoft Corp. (Summer 2006): Developed tools and methodology to analyze the quality of the index of Windows Live Search based on the static rank distribution of the pages. This involved collection and analysis of the appropriate metrics for documents in the entire index data and and identify possible solutions to make the index generation pipeline more efficient.
  • Intern in MSN Search at Microsoft Corp. (Summer 2005): Developed a tool that measures of the effect of query rewriting on the relevance of the results in a search engine. The tool automatically suggests the rewriting options with synonyms and co-occurring terms with the query terms that improve the relevance of the results.
  • Research Scientist in Data Mining Research Group at Humana Inc. (Summer 2004): Developed a system that visualizes and analyzes the disease conditions of health insurance members based on their medical and pharmacy claims. Devised Bayesian Vector Autoregression (BVAR) model to forecast claim costs and health conditions. This system helps in identifying the potential sick customers that can be helped by a dedicated personal nurse program.
