Microsoft Bing, Software Developer Intern I worked on the index sorting problem with the Relevance Infrastructure team. My experiments showed that a Neural Network that re{orders the indexed documents based on a combination of document static features, click-through data and other popularity signals can significantly improve the performance of document matching and ranking.	Summer 2009
Microsoft Live Search, Software Developer Intern I worked on extracting statistically significant phrases from search results titles and snippets. These are typically interesting phrases that users can use to refine their queries. I also developed an online clustering module which analyzes search results and shows a label for each cluster. Labels can be used by users in refining their queries.	Summer 2008
