Education

Ph.D., 2002, Indiana University at Bloomington (Speech and Hearing Science)

B.S., 1997, Peking University (Physiology and Biophysics)

 

Research Interests

Basic research interest includes the perception of speech and non-speech complex sounds, for native and non-native listeners, for normal-hearing and hearing-impaired listeners, speech intelligibility of non-native speakers, auditory model for speech processing, development of speech perception and speech production, and speech synthesis and recognition. Recent studies have been focusing on vowel perception, bilingual speech production and perception, spectral enhancement, auditory models of speech processing for normal-hearing and hearing-impaired listeners and auditory processing for young children.

 

Current Projects

Speech production and perception of English non-native speakers

Speech enhancement for speech perception in noise for normal-hearing and hearing-impaired listeners

Mandarin Chinese speech perception for different populatoins: young and elderly; normal- and impared hearing

Tone perception for normal-hearing and hearing-impaired listeners, for Chinese and English listeners, and for clincial populations with amusia and tone agnosia
