Ray Munguia-Vazquez, MD PhD
Adjunct Clinical Assistant Professor of Otolaryngology-Head & Neck Surgery
I am a clinical assistant professor of otolaryngology-head and neck surgery at IU School of Medicine-West Lafayette and in the Speech-Language and Hearing Sciences department at Purdue University. Since January 2013, I have taught courses in advanced electrophysiology, auditory and vestibular pathology, research, and medical audiology.
I am developing my research program to understand better how the auditory cortex adapts and responds to different pathological conditions such as auditory processing disorders (ADP) and sensorineural hearing loss, as well as in tinnitus and hearing loss following mild traumatic brain injuries. The primary goal of this research is to establish, with the aid of electrophysiological recordings, new protocols for early diagnosis and intervention in individuals with these disorders.
