Biography

Xin joined the Department of Speech and Hearing Science at Arizona State University in 2015. He completed his Ph.D. thesis on speech processing strategies for Mandarin-speaking cochlear implant users, and received post-doc training on speech perception and auditory psychophysics with cochlear implants, both at the House Ear Institute in Los Angeles. His current research focuses on understanding the basic mechanisms of pitch perception in both acoustic and electric hearing, and on using such knowledge to develop novel sound processing strategies that can enhance speech and music perception for cochlear implant users. 

Research Interests
