Welcome to my home page

I have completed my PhD from University of Maryland College Park, working with Prof Rama Chellappa. After a short stint with Amazon's A9.com developing algorithms for large scale image match, I am now working with the StreetView team in Google.

I specialize on developing fast and efficient machine learning algorithms for image data.

My research interests are
  •  Computer Vision,
  •  Machine Learning and
  •  Biometrics.
