I have a broad interest in all kinds of real world applications that are related to effectively and efficiently managing large amount of text information. My primary research interest is information retrieval. I am also interested in bioinformatics, data mining and databases.

I am actively recruiting students interested in information retrieval, search engine technologies, and related areas. Please just drop me a message, I will be happy to chat with you and give you an overview of my research.
