Meet Our Team

Ronna Hertzano, MD, PhD

Ronna Hertzano, MD PhD - Principal Investigator

Dr. Hertzano is an otolaryngologist surgeon-scientist tenured Associate Professor at the Department of Otorhinolaryngology Head and Neck Surgery, the University of Maryland School of Medicine. Born in Israel, Dr. Hertzano received her M.D. and Ph.D degrees from the Sackler School of Medicine at Tel Aviv University, Tel Aviv, Israel. Her doctoral thesis, which was performed both at Tel Aviv University and at the National Institutes of Deafness and Communications Disorders (NIDCD/NIH) focused on elucidating the signaling pathway downstream of the deafness causing gene POU4F3 in the mouse inner ear. She then performed her residency training in Otolaryngology Head and Neck Surgery at the University of Maryland School of Medicine, where she also established her research team.

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. The goal of Dr. Hertzano’s research program is to make significant contributions towards the treatment of congenital and acquired auditory and vestibular dysfunction. Towards hearing restoration, she works to unravel the regulatory signaling cascades that lead to the proper development of the ear and specifically the hair cells. A second main interest is in developing therapeutics to prevent age and noise induced hearing loss. To facilitate dissemination, sharing and analysis of multi-omic data Dr. Hertzano developed the gEAR portal – gene Expression Analysis Resource (umgear.org). Finally, Dr. Hertzano has a strong interest in mentorship. Her diverse team consists of undergraduates, medical students, residents, audiologists, graduate students, and post docs.

Dr. Hertzano is the recipient of several awards including the Burt Evans Young Investigator Award, from the National Organization of Hearing Research; Brian E. Emery, M.D., Outstanding Teaching Award, UMSOM; and Distinction Award in Alternative/Basic Science for the Triological Society Thesis. Dr. Hertzano is chair of the American Neurotology Society research committee; core faculty of the University of Maryland College Park Center for Comparative and Evolutionary Biology of Hearing T32 grant; a member of the Hearing Restoration Program of the Hearing Health Foundation, and an organizing committee member of the HEAR@JAX workshop of the Jackson Laboratory, Bar Harbor, Maine. In her free time, Dr. Hertzano enjoys running, cycling, and playing Rummikub.

Elena was born in London, England. She received her undergraduate degree in Physiology and her master’s degree in Molecular Neuroscience at the University of Bristol. She completed her Ph.D. in Auditory Neuroscience at the UCL Ear Institute. Her Ph.D. research involved visualizing the dynamics of Notch signaling and investigating the mechanism of Delta-like1 during the development of the chick inner ear sensory epithelia. Elena completed a post-doctoral fellowship at John’s Hopkins University where she investigated the roles of Jagged1 during supporting cell development in the mouse inner ear. Elena joined as a post-doctoral fellow in the Hertzano Lab in 2020 to expand her knowledge of genomics and bioinformatics and to contribute to the development of a multi-omics data portal for Alzheimer’s disease (NeMO-AD). In her free time Elena enjoys salsa dancing, attending concerts, and cooking.

Katie Gwilliam, BS - Fourth Year PhD Student

Katie is a fourth year Human Genetics, PhD student at the University of Maryland, Baltimore. She received her B.S. in Biology, with a concentration in Biotechnology and Molecular Biology, and minor in dance at George Mason University. Katie studies the genetics and molecular mechanisms of inner ear development and hearing loss. More specifically, she researches the roles of specific transcription factors, such as the Regulatory Factor X (RFX) transcription factor family, in hair cell development and maintenance of the cochlea and vestibular system using mouse and zebrafish models. Katie is known as the lab’s baker and provides the lab with sweet treats for meetings, holidays, and more.
Kevin Rose, BS - Third Year PhD Student

Kevin Rose, BS - Third Year PhD Student

Kevin Rose obtained his bachelor’s degree in health sciences from the University of Cincinnati in 2012. He joined Dr. Hertzano’s lab as a graduate student in July 2018 to undertake a project that involved both wet lab and bioinformatic techniques. His current research project focuses on the otic mesenchyme specific transcription factor, Pou3f4. With techniques such as scRNA-seq, scATAC-seq, and CUT&RUN, he is unraveling the gene regulatory network downstream of Pou3f4, leading to novel deafness genes. In his free time, Kevin enjoys playing basketball, long walks with his dog, and video games.
