I am a Principal Applied Scientist at Bing in Microsoft Research Cambridge. My research is focused on Web search, information retrieval and machine learning. I started at Bing in 2007 (then called Live Search) at the Search Technology Center in India. Since then I have worked on a number of problems related to document ranking, query formulation and recommendation, query re-writing, entity ranking and evaluation. My current research interests center on representation learning and in particular their application to modern day information retrieval.
