Dr. Hertzano is an otolaryngologist surgeon-scientist. Dr. Hertzano obtained her M.D. and Ph.D. degrees from the Sackler School of Medicine, Tel Aviv University where her research work was performed under the supervision of Prof. Karen B. Avarham. Dr. Hertzano then pursued a clinical residency in otolaryngology Head and Neck Surgery at the University of Maryland School of Medicine, Baltimore, followed by advanced training in Neurotology under the supervision of Dr. David J. Eisenman, where she continues to practice to this day. Dr. Hertzano's clinical practice focuses on the diagnosis and treatment of diseases of the ear, with a specific emphasis on hearing restoration. As such, she sees and treats patients of all ages that suffer from hereditary and non-hereditary auditory and vestibular dysfunction. In parallel to her surgical practice, Dr. Hertzano leads a vibrant research team where her goal is to make significant contributions toward the treatment of congenital and acquired auditory and vestibular dysfunction. Towards hearing restoration, she words to unravel the regulatory signaling cascades that lead to the proper development of the ear and specifically the hair cells. Her team develops and applies a variety of approaches for cell type-specific genomic analysis of the ear. The results of these studies are coupled with informatics analyses to identify key regulators of gene expression in hair cell development, and cell type-specific signaling cascades in acquired hearing loss. In addition, the team leads an effort to facilitate data sharing and visualization through the development of and maintenance of the gEAR - a portal of gene Expression for Analysis Resource (UMgEAR.org). Finally, Dr. Hertzano has a special interest in mentoring undergraduates, medical students, residents, graduate students, and post-docs. Dr. Hertzano's work is supported by the National Institutes of Health, the Department of Defense, and the Hearing Restoration Project (Hearing Health Foundation).
