Professor David K. Ryugo
Curran Foundation Chair of Neuroscience, Garvan Institute of Medical Research; Conjoint Professor, School of Medical Sciences, The University of New South Wales; Principal Honorary Fellow, Bionic Ear Institute, Melbourne Victoria, Professor (retired and part time), Departments of Otolaryngology and Neuroscience, Johns Hopkins University USA

Research Group: Hearing Research
David spent 9 years on the faculty at Harvard Medical School and 23 years at Johns Hopkins University School of Medicine before joining the Garvan. His research focuses on understanding brain mechanisms of hearing, and he studies structure-function relationships in neuronal circuits of the auditory system. David is especially interested in how deafness and hearing loss alter brain organization, and in exploring strategies for hearing restoration.
