I am a principal research staff member in the speech group of the IBM T. J. Watson Research Center. My research interests include automatic speech recognition (particularly noise robustness and speaker adaptation), multi-lingual speech-to-speech translation, digital speech processing, statistical signal processing, machine learning and pattern recognition. Most recently, I have been working on deep learning in speech applications.
I received my B.S. degree from Shanghai Jiao Tong University, Shanghai, China, M.S. degree from Tsinghua University, Beijing, China, and Ph.D degree from University of California, Los Angeles, all in electrical engineering.
