Brian R. Earl, PhD; Director of EARLAB

Biographical Sketch

Dr. Earl recently began a position as Assistant Professor of Audiology in the Department of Communication Sciences & Disorders. Previously, Dr. Earl was a postdoctoral fellow in the Hearing & Speech Department at the University of Kansas Medical Center where he was involved in translational research focused on the diagnosis of hearing loss.  

Dr. Earl completed a PhD in Audiology at the University of Kansas after working for three years as a clinical audiologist at the University of Texas Medical Branch.  He also holds Masters and Bachelors degrees in Audiology from the University of Arizona and Brigham Young University, respectively.    

His current research efforts at UC are focused on developing a clinical test of auditory nerve survival that may help tailor treatment options to individuals with hearing impairment.

Research Activity Summary  

My research is focused on developing diagnostic measures of auditory nerve survival in individuals with hearing impairment. Specifying the pathophysiology leading to hearing impairment may help clinicians individualize amplification and cochlear implant algorithms.  

To accomplish this objective, proof-of-concept experiments involving physiologic and anatomic measures are being completed in animal models of partial auditory nerve lesions. The physiologic measures include otoacoustic emissions and auditory evoked potentials.  Anatomic measures involve confocal imaging of cochlear hair cells and auditory neurons.

My current research efforts are supported by start-up funds from the University of Cincinnati’s Vice President for Research.  Funding is available for a research assistant at the undergraduate or graduate level.
