Wang at Johns Hopkins University (JHU) Laboratory of Auditory Neurophysiology, and recently transfered to the Hermanski speech research lab at JHU.

Update on Jul 22, 2012: After finishing my PhD, I spent one and a half year learning auditory neurophysiology at the Center for Hearing and Balancing of Johns Hopkins School of Medicine, where I was working on a project aimed to determine the functionality of auditory cortex in primate vocal communication by using a multi-channel wireless neural recording system implanted in the head of free-roaming marmosets. Then I joined the Center for Language and Speech Processing and began working on automatic speech recognition under the supervision of Dr. Hynek Hermansky. Meanwhile, I am working on two projects, one DARPA project on noise-robust speech recognition, with an aim to build a bio-inspired parallel sub-band phoneme recognition system; and the other on spectral and temporal modulation, for which I am planning to apply for financial support. Our aim is to identify the spectral and temporal components that are important for speech recognition in realistic listening condition.
