Nina Kraus, PhD is Director of the Knowles Hearing Center and Professor of Communication Sciences, Neurobiology, and Otolaryngology at Northwestern University. As a biologist and amateur musician, she thinks about sound and brain health.

Her research has found that our lives in sound, for better (musicians, bilinguals) and for worse (concussion, hearing loss, language disorders, noise), shape how our brain makes sense of the sounds we hear. Her book OF SOUND MIND - How our Brain Constructs a Meaningful Sonic World, was written for the intellectually curious.

Kraus advocates for biologically informed choices in education, health, and society. See www.brainvolts.northwestern.edu
