My research focuses on the neural mechanisms underlying auditory scene analysis and speech perception in “cocktail-party” environment, with special emphasis on the interaction between auditory "what", "where" and "how" neural pathways which engages in encoding sound identity, spatial processing, and sensorimotor integration, respectively. I use a combination of neuroimaging techniques (e.g., MEG, ERP and fMRI) to investigate which, and how, different brain areas are recruited and modulated by attention and perceptual learning in processing speech identity and/or location. Also I am interested in how the auditory-motor areas, which are involved in speech production, contribute to speech perception in demanding circumstance and how this function is influenced by cognitive aging.
