Research Interests: Our lab is interested in the cellular and molecular mechanisms underlying tissue damage in both peripheral and central auditory structures. We focus on molecules that have roles in normal audition as well as tissue destruction due to inflammation, noise exposure and aging. We are currently studying the roles of two small families of molecules, the nitric oxide synthase proteins and the synuclein proteins. Our goal is to relate changes in auditory sensitivity to cellular damage and alterations in the expression of these proteins. For more information visit Dr. Faddis' Lab
