Darlene R. Ketten, Ph.D.


Darlene R. Ketten, Ph.D., is a neuroanatomist specializing in comparative evolution of hearing and mechanisms of hearing loss. She received a B.A. from Washington University (Biology and French), a M.S. from M.I.T. (Biological Oceanography), and a Ph.D. from Johns Hopkins Medical Institutions, The Johns Hopkins University (jointly awarded in neuroanatomy, behavioral ecology, and experimental radiology). She currently holds joint appointments as a Senior Scientist in Biology at Woods Hole Oceanographic Institution, as Assistant Clinical Professor in Otology and Laryngology at Harvard Medical School, and as a Senior Research Fellow at National Institutes of Health/National Institutes of Deafness and Other Communication Disorders (NIH/NIDCD). She is also the director of a research facility for head and neck imaging, the Computerized Scanning and Imaging Laboratory (

Her current research focuses on modeling underwater hearing ranges of marine mammals, which have the most extreme mammalian auditory system adaptations known, and on diagnostic imaging and assessment of ear trauma and disease. She has completed medical specialty accredidation courses in Otopathology, Neuroradiology, and Forensic Pathology and is a Fellow of the Acoustical Society of America. Dr. Ketten is an active member of US Federal and International advisory boards and panels on hearing, bioacoustics, acoustic trauma, and marine mammal regulatory guidelines. She has been a voting member and specialty panelist for the National Institutes of Deafness and Communication Disorders, the National Academy of Sciences, the Marine Mammal Commission, NATO, the U.S. House of Representatives, the U.S. Senate, and the Acoustical Society of America. Dr. Ketten has over twenty years experience in the combined fields high resolution radiology, auditory system modeling and head and neck pathology. She has over 100 peer reviewed publications and case studies as well as authoring multiple specialist review articles and book chapters on imaging, diagnostics of auditory system pathology and hearing mechanisms.
