Research Interests / Training Areas:
- Cochlear implants
- Speech perception
- Pitch and lexical tones
Xin Luo received his Ph.D. in Electrical Engineering from the University of Science and Technology of China in 2005, after completing the thesis research on speech processing strategies for Mandarin-speaking cochlear implant users at the House Ear Institute. He received post-doc training in speech perception and auditory psychophysics with cochlear implants at the same institute before joining the Department of Speech, Language, and Hearing Sciences at Purdue University in fall 2008.
Dr. Luo's research focuses on the mechanisms of pitch perception with normal hearing and cochlear implants, and signal processing techniques to enhance pitch perception in speech and music for cochlear implant users. His research approach uses speech perception tests with clinical cochlear implant processors, psychophysical and electrophysiological measures with cochlear implant research interface, and computational models of cochlear implant stimulation.
