My research aims to understand how dynamic functions of the human brain support speech communication. How do we make sense of speech sounds? How do cognitive mechanisms like attention and working memory contribute to spoken language? How do our prior experiences and auditory expertise shape speech processing and representation? To better understand the dynamic neural interactions between auditory perception and high-level cognition, my research program investigates how sound categories are learned, how speech is remembered, and how we pay attention to different talkers. Our research integrates theoretical models from cognitive science and empirical approaches from cognitive neuroscience, including psychophysics and psycholinguistics paradigms, multimodal EEG and fMRI neuroimaging, pupillometry, and computational modeling.
