I am a graduating PhD student in the CIIR lab, working with Prof. James Allan. My thesis is about the bias-specific diversification of search results for non-topical dimensions such as sentiments and time.
I am interested in solving real world problems in Information Retrieval and Natural Language Processing. I have worked in question answering, passage retrieval, language modeling, sentiment analysis, sparse queries, personalization, outlier detection, and diversification.
Here is an information retrieval (IR) glossary for new IR students.
I spent the summer of 2011 at Yahoo! Search working with great researchers in the User Intent Analysis team.
I developed algorithms for the Misfit Mode in IBM Many Bills at the Visual Communication Lab of the IBM Watson Research Center during the summer of 2010. I am very happy to see my work go into production!
