Sound-induced plasticity of the lateral olivocochlear efferent system

The lateral olivocochlear (LOC) efferent system is thought to modulate inner ear function to support hearing-in-noise and protect against noise damage, yet its precise role remains unclear. In this study, we are investigating how sound exposure alters LOC neurotransmitter expression and how these changes affect physiological and behavioral measures of hearing-in-noise. We are also investigating whether sound-induced LOC plasticity occurs in damaged ears. This work is currently funded by an Emerging Research Grant through the Hearing Health Foundation.

Comparative studies of the olivocochlear efferent systems

Much can be learned about the structure and function of neural pathways by comparing across species. In this study, we are characterizing the anatomy of the medial and lateral olivocochlear efferent systems across animal models, including rodents and nonhuman primates. We are also interested in expanding this work to include nontraditional model species.

Environmental sound monitoring

Sound experience varies extensively across listeners. Our lab utilizes laboratory and wearable technologies to perform continuous monitoring of sound environments, both for animals and humans.

Audiology education

The field of clinical audiology changes rapidly, with continuous advancements in medicine and technology. Graduate education in audiology transitioned to a doctoral degree (Au.D.) approximately two decades ago, with the goal of elevating training and enhancing long-term success of the profession. However, little work has investigated the efficacy of this change and current educational practices in Au.D. programs. This line of research aims to characterize current educational practices in order to improve the didactic training of audiology professionals, particularly in emerging areas such as neuroscience, genetics, and pharmacology.
