Basic Science Research
Basic science researchers in the Caruso Department work collaboratively
Using the latest technology in genetics, stem cell medicine, neuroscience and biomedical engineering, researchers find advanced solutions for disorders of the head and neck.
Our Labs & Facilities
John S. Oghalai, MD
The Oghalai lab at the Zilkha Neurogenetics Institute seeks to better understand the fundamental changes in cochlear function that underlie progressive hearing loss and to develop novel techniques to treat this problem before it leads to deafness. Clinically, our ultimate goal is to improve human health not only by caring for our patients expertly, but also by advancing our scientific knowledge base so that all physicians can treat disease more effectively.
Carolina Abdala, PhD
The Abdala Lab, within the USC Caruso Department of Otolaryngology, studies natural changes in cochlear mechanics throughout the arc of the human lifespan. This research aims to provide a normative framework, but also to explore the mechanisms driving such change. Recent work is focused on the potential development and application of a combined reflection (SFOAE) and distortion (DPOAE) OAE protocol to understand and describe underlying deficits, not just detect and label sensorineural hearing loss.
Christopher Shera, PhD
The Auditory Physics Group in the Caruso Department of Otolaryngology works to solve fundamental problems in the mechanics and physiology of the auditory system. Current interests of the group include comparative cochlear mechanics, cochlear nonlinearity and amplification, middle-ear mechanics, and otoacoustic emissions.
Radha Kalluri, PhD
The Kalluri Lab at the Zilkha Neurogentic Institute, led by Radha Kalluri, PhD, assistant professor of otolaryngology, explores the cochlea, an elegant hydromechanical structure in the ear, that which works to separate sounds of different frequencies and maps them onto a different place on the sensory epithelium. Specialized sensory cells that provide feedback forces to actively amplify local mechanical resonances refine this frequency-place map within the cochlea. Research is focused on understanding the biophysical mechanisms by which the auditory periphery parses frequency and intensity information, and how these
functions degrade with hearing loss.
Neil Segil, PhD
The Segil Lab at the Eli and Edythe Broad Center for Stem Cell Research and Regenerative Medicine, led by Neil Segil, PhD, professor of research stem cell biology & regenerative medicine, otolaryngology, explores the death of sensory hair cells in the inner ear and their failure to regenerate – the major cause of deafness. The long-term goal of the laboratory is the treatment of deafness through regeneration of these sensory hair cells.
