Welcome to the Peelle Lab, in the Department of Otolaryngology in the medical school of Washington University in Saint Louis.

Our research is focused on the neurobiology and psychology of speech comprehension, and how this is affected by changes in cognitive and hearing ability. We study speech and auditory processing in adults of all ages and varying levels of hearing, using a combination of behavioral testing and brain imaging to investigate the cognitive processes involved in speech comprehension. Some of the brain imaging techniques we rely on are structural magnetic resonance imaging (MRI), functional MRI, and high-density diffuse optical tomography (HD-DOT).
