Research Interests: My core research area is Information Retrieval (IR) which is the technology behind search engines, such as, Google, Bing, Lucene, and Indri. Within IR I am interested in the problems that arise when searching large document collections (e.g. half a billion webpages) using limited amount of computing resources (e.g. handful processors). It is an exciting time to work on these problems since increasing number of organizations are digitizing vast amounts of data and need search solutions that balance efficiency and effectiveness, and do not require large computing clusters.

Previously I have worked on, and continue to be interested in, research problems in natural language processing and machine learning.
