Andrew Senior received his PhD from the University of Cambridge, for his thesis "Offline cursive handwriting recognition with recurrent neural networks", having previously worked on speech recognition at LIMSI at the University of Paris XI. He joined IBM Research in 1994 where he worked in the areas of handwriting, audio-visual speech, face and fingerprint recognition as well as video privacy and visual tracking. In 2008 he taught at Columbia University before joining Google Research where he worked on speech recognition with deep neural networks and recurrent neural networks. He has coauthored a "Guide to Biometrics", and over seventy scientific papers; holds forty-six patents. His research interests range across deep learning, speech, computer vision and visual art.
