Professional Interests

Research Interests
Hearing loss is the third most prevalent chronic health condition, causes individuals to understand speech poorly, and affects the quality of life in older adults. The most common type of permanent hearing loss is sensorineural hearing loss that results from damage to the cochlea, and/or to the auditory nerve pathways from the cochlea to the brain. Sensorineural hearing loss is caused by several contributing factors such as aging, ototoxic chemicals, noise exposure, and/or genetic conditions. Work in my Laboratory is focused on understanding the molecular and cellular mechanisms that underlie age-related hearing loss using various transgenic and knockout mice. A second question being studied in my laboratory is how the cochlea protects itself from endogenous and exogenous toxins throughout the lifespan. We are also interested in understanding the molecular mechanisms underlying the beneficial effects of physical activity on auditory function.
