John J. Rosowski, PhD

The Transmission of Sound to the Cochlea in Normal and Pathological Human Ears

Dr. John J Rosowski is a Professor Emeritus of Otolaryngology and Head & Neck Surgery at the Harvard Medical School (HMS) and a semi-retired Principal Scientist at the Massachusetts Eye and Ear Infirmary (MEEI) in Boston MA. His PhD, received in 1979, is in Physiology from the University of Pennsylvania, with Dr. James C Saunders as his supervisor.  A three-year post-doctoral fellowship in Physiologic Acoustics at the Massachusetts Institute of Technology in Cambridge MA followed, under the supervision of Professor Bill Peake. An appointment as Research Scientist at MIT in 1983 was followed by a switch to Associate Profess of Otology and Laryngology at HMS and the MEEI in 1993. He has remained with the HMS and MEEI since.

The central theme of Dr. Rosowski’s research career has been the relationship between the structure of external and middle ear systems within humans and other vertebrates and their physical and physiological function. His work includes acoustical, mechanical and physiological measurements in the middle ears of lizards, birds, common laboratory mammals, and a few more exotic mammals, including lions, and tigers. This interest in how middle-ear form affects its function has been generalized to include speculations about how the transition of the ossicles from the jaw of early mammal-like reptiles to the mammalian middle ear influenced hearing function, and, in-consort with his clinical colleagues at the MEEI, numerous studies of how common pathologies and surgical reconstructions affect human middle-ear function. 

Dr. Rosowski has applied innovative tools in his studies.  These include measurements of sound pressures within the inner ear, wide-band acoustic immittance, laser-Doppler vibrometry, laser-holography and optical-coherence tomography. In recent years he has worked with students and young colleagues to better understand the response of the human and animal ears to bone-conducted stimuli, especially at high frequencies.

In performing his work Dr. Rosowski has depended on and greatly benefitted from the efforts of his many colleagues (Bill Peake ScD, Saumil Merchant MD, Tom Weiss ScD, Michael Ravicz MS, Heidi Nakajima MD PhD, Sunil Puria PhD, Jeffry Tao Cheng PhD, Cosme Furlong PhD, Aaron Remenschneider MD MPH and others) and students and advisees (Susan Voss PhD, Greg Huang PhD, Jocelyn Songer PhD, Gabriel Merchant PhD, David Chhan MS, Peter Bowers PhD and many more).

Larry Hoffman, Ph.D.

Investigations of vestibular hypofunction provide insights into rehabilitation and neurocomputation.

After completing the doctorate in physiology from the University of California at Davis (John Horowitz, Tim Jones), Larry Hoffman joined the laboratory of Vicente Honrubia in the Department of Surgery/Head & Neck Surgery at the UCLA School of Medicine to investigate the morphologic substrates of dynamic response heterogeneity among vestibular primary afferent neurons. Upon establishing an independent laboratory at UCLA he began collaborating with Michael Paulin (University of Otago; Dunedin, New Zealand), taking a different approach to probing head movement coding and the role of spontaneous discharge in sensory information transmission and dynamical sensory coding. The laboratory’s focus on ribbon synapses in vestibular hair cells began with a spaceflight investigation in which plasticity in synaptic ribbon densities was found after a 2-week exposure to the microgravity environment of the International Space Station. Much of the lab’s current work is focused upon the physiologic and cellular substrates of vestibular function and hypofunction, including those associated with behavioral agility and hypofunction induced by ototoxins and genetic modification. This research provides a rich platform revealing novel insights into rehabilitation and neurocomputation.

Tejbeer Kaur, Ph.D.

Diversity and Function of Microphages in Normal and Damaged Ears

Dr. Tejbeer Kaur is an Indian immigrant and an Assistant Professor of Biomedical Sciences at Creighton University in Omaha Nebraska. She obtained her PhD at the Southern Illinois University, Springfield, Illinois where she studied the role of inflammation and STAT transcription factors in cisplatin (cancer drug)-induced ototoxicity and hearing loss. She completed postdoctoral training at Washington University, St. Louis, Missouri. In the Kaur Lab, the research aims to understand the complex biology and interactions of immune cells and their effector molecules with the sensory cells in the cochlea of the inner ear and how these interactions influence hearing, hearing loss and sensory cell development, degeneration, repair, survival, and plasticity. Inner ear contains a resident population of macrophages (innate-immune cells). Importantly, sensorineural hearing loss due to ototoxic side effects of certain medications, noise trauma, infections or healthy aging is associated with inflammation and robust activation and increase in numbers of macrophages. However, the precise functions of macrophages and inflammation are unclear. Dr. Kaur’s early research demonstrated a critical role of macrophages in the survival of afferent neurons in the injured cochlea and identified a novel neuron-immune signaling axis, fractalkine signaling that regulate the spontaneous repair of ribbon synapses and long-term survival of neurons in the injured cochlea. Recently, she and her colleagues have delineated a new role for cochlear macrophages in ribbon synapse repair after noise-induced synaptopathy. Her ongoing work focuses on understanding the diversity and functions of macrophages and their effector molecules in normal and pathological ears and to develop novel immunotherapies to prevent and/or restore loss of hearing and sensory cells and to maximize hearing aids and cochlear implant technologies for treating sensorineural hearing loss.
