His thesis was on automatic speech recognition, Acoustic Modelling for Automatic Speech Recognition: Deriving Discriminative Gaussian Networks. He did research for his thesis at Nuance Communications while working there as an intern, and after graduating he joined Nuance as a speech engineer until 2001.
