Multisensory Integration and Neurocognitive Dynamics Lab

The Multisensory Integration and Neurocognitive Dynamics Lab investigates how auditory, visual, and tactile systems develop, process, and integrate sensory information across the lifespan to support speech perception, communication, cognitive function, and auditory rehabilitation.

Yi Yuan, Ph.D.

Assistant Professor
Director, Multisensory Integration and Neurocognitive Dynamics Lab

Dr. Yi Yuan studies the neural and cognitive mechanisms that support speech perception, auditory processing, and communication in complex listening environments. Her research examines how auditory and multisensory systems develop and change across the lifespan, how the brain represents the temporal and structural features of speech, and how cognitive functions such as attention and listening effort contribute to auditory perception. She is particularly interested in how auditory, visual, and tactile information are integrated to support speech understanding and how these sensory and cognitive processes contribute to individual differences in communication outcomes.

Her work includes cochlear implant users, listeners with hearing loss, and individuals with auditory or neurodevelopmental conditions. She uses behavioral measures, auditory electrophysiology, functional near-infrared spectroscopy, and other neurotechnologies to study neural encoding, multisensory integration, auditory plasticity, and speech perception in noise.

Dr. Yuan’s research seeks to improve auditory rehabilitation and develop individualized approaches to communication support, including multisensory and technology-assisted interventions.
