About Me

I am currently a member of Microsoft adCenter Labs, the research arm of Microsoft adCenter. Our role is to advance the state-of-the-art in digital advertising technologies through  research, breakthrough innovation, rapid prototyping, and large-scale system integration.

Till very recently (July 2006) I was a part of "Knowledge Tools Research" group at Microsoft Research. We used machine learning to demystify complex data sets encountered by people on a daily basis e.g. email, news, etc. Before joining MSR in November 2002, I was at Bell Labs working on speech and speaker recognition in the the now defunct Multimedia Communications Research Laboratory. I got my Ph.D. from Rutgers, The State University of New Jersey. There, I worked at the Center for Advanced Information Processing (CAIP). I got my bachelor's degree from the Indian Institute of Technology-Roorkee (formerly University of Roorkee).

I am a Senior Member of the IEEE. I recently finished my term as Associate Editor for the IEEE Transactions on Speech, Language and Audio Processing.

Research Interests:

The overarching theme of my research is to solve problems involving large complex data using machine learning and data mining, to make people more productive, and their lives a bit easier.

• Machine learning algorithms for solving problems in online advertisement & monetization
• Social intelligence
• Text mining & analysis: text categorization, clustering, keyword extraction, evolving and growing topic models, applications such as email mining & Tagging
• SDPs and other optimization problems
• Speech & speaker recognition
