I have been working at Yahoo from 2005 in the search division. I have worked on the vertical search relevance projects and the Vespa team for a little over 3 years for improving the relevance of the search result ranking of the vertical properties. Currently am working in the spelling team in the Search science division. Prior to joining Yahoo, I have worked at Argonne National Laboratory on data mining projects. I have received my masters in computer science in 2004 from University of illinois at Chicago. My interests involve machine learning, data mining and information retrieval methodologies.
