I am a Research Engineer at Microsoft Research where I work on large scale recommendation problems. My work has an intersection between machine learning and efficient system design. I work on developing and deploying Extreme Classification (XC) algorithms with guidance from Manik Varma. Algorithms developed by me are deployed on Bing, MSN and other Microsoft products where they are helping billions of users and (in-process) generating millions of dollars in revenue by showing more relevant and presonalized recommendations.
