Short Bio

I am a PhD candidate in the Computer Science and Engineering department of IIT Bombay, since Autumn 2011, through a joint co-op program with Yahoo! Labs. My advisor is Prof. Soumen Chakrabarti from IITB and my co-advisors are Dr. Peter Mika and Dr. Roi Blanco from Yahoo! Labs, Barcelona.

Prior to joining PhD program, I was working as a research engineer at Yahoo! labs, Bangalore. I obtained a master's degree from CSE department, IIT Bombay, in 2008. Here is my resume in html and pdf.

Research Topic

Web search views the Web as a collection of documents and returns a list of documents ranked in the order of relevance to the user query. Identification of objects or concepts in a document (people, places, cars etc) allows us to do more; such as providing direct answers to many user queries. I am interested in this kind of "Entity search". I am currently studying the query interpretation and ranking components for the same.
