I was a PhD student in the Language Technologies institute which is part of the School of Computer Science at Carnegie Mellon University, advised by Prof. Bhiksha Raj. I worked on privacy preserving machine learning for speech processing in the Secure Audio project.
I completed my PhD thesis in April 2012 and it was selected to be published in the Springer best thesis series.My research on privacy-preserving speaker verification received significant press coverage.
