Dr. Gallun is a full-time research investigator at the National Center for Rehabilitative Auditory Research, located at the Portland VA Medical Center as well as Associate Professor in Otolaryngology at OHSU. His laboratory, located at the VA Medical Center, makes use of an anechoic chamber for human behavioral studies as well as computer-controlled headphone and electrophysiological experiments using non-invasive techniques with patient populations as well as healthy volunteers.

The focus of the Gallun lab is to understand the impacts of age, hearing loss, and traumatic brain injury on central auditory function. The main areas of study are 1) binaural sensitivity and the ability to benefit from spatial separation of sound sources, 2) temporal processing, and 3) speech understanding. Most projects involve a combination of two or more of these areas and the testing of patients who differ from young, normal hearing listeners on one or more attributes.
