Biography:

I received my Bachelors degree (B.E) in Electrical and Electronics Engineering from Bangalore Institute of Technology, Bangalore , in 2004, and my MSc degree in Digital Signal Processing from Queen Mary, University of London in 2005. During my MSc thesis I worked in liaison with the Institute of Dentistry , at Barts and The London, Queen Mary's School of Medicine and Dentistry, in designing an intuitive approach for the registration of 3D face scans with deformations.

In 2009 I completed my PhD research at Queen Mary, University of London under supervision of Prof. Andrea Cavallaro. During my PhD I worked on the analysis of 3D face scans, primarily focusing on registration, deformation analysis and automatic detection of facial landmarks. An algorithm was developed for the detection of landmarks and the segmentation of regions on 3D facial scans that, unlike previous approaches, is independent of texture, pose or orientation information. This was used to develop further algorithms for face segmentation (detection) in 3D scenes and expression-invariant face recognition.

I'm currently working as a Teaching/Research Assistant in the School of Electronic Engineering and Computer Science, Queen Mary, University of London.
