I am a researcher in Google AI Perception in Cambridge, Massachusetts where I lead a research team in the area of speech and audio machine perception. Prior to Google I spent seven years leading the speech and audio research team at MERL (Mitsubishi Electric Research Labs), and five years at IBM's T. J. Watson Research Center in New York, where I led a team of researchers in noise-robust speech recognition. I also spent a year as a visiting researcher in the speech group at Microsoft Research in 2004, after obtaining my Ph D from UCSD. Over the years I have contributed to more than 100 publications and over 30 patents in the areas of machine perception, speech and audio processing, audio-visual machine perception, speech recognition, and natural language understanding.
