About me: Our research focuses on nonlinear dynamical aspects of vertebrate’s auditory system revealed by otoacoustic emissions, low-amplitude sounds produced actively by the inner ear. We employ a theoretical framework of coupled nonlinear oscillators to investigate the collective dynamics of hair cells that underlie the exquisite detection threshold and time-frequency resolution of the inner ears. Our laboratory also performs behavioral studies of speech perceptions in an anechoic environment as another tool to reveal nonlinear characteristics of human’s auditory system.
