Marc Fagelson, PhD is the Director of Audiology, Assistant Chair, and Professor in the Department of Audiology and Speech-Language Pathology at East Tennessee State University. His clinical and academic teaching centers on courses covering audiologic evaluation, pathologies of the auditory system, and tinnitus management. Dr. Fagelson's work with tinnitus patients at the James H. Quillen Mountain Home VAMC tinnitus clinic began in 2001 and was motivated by tremendous need among the veteran population; the clinic now enrolls more than 800 patients. A substantial proportion of the veterans experience tinnitus that is complicated by the influence of posttraumatic stress disorder. This challenging and underserved population is the focus of Dr. Fagelson's research.
