Dr. Champlin's research focuses on physiological correlates of auditory perception, the effects of noise on hearing, spectro temporal processing of sound, and otoacoustic emissions. He has received numerous research grants, most of which have targeted the study of auditory evoked potentials in humans. He has also published research articles in the Journal of the Acoustical Society of America, Hearing Research, the Journal of Speech and Hearing Research, and others. In addition, Dr. Champlin has been a consultant on projects dealing with community noise issues, hearing conservation education in children, and infant hearing screening. He teaches courses in hearing science, instrumentation, electrophysiological audiometry, and hearing conservation. As a member of the Institute for Neuroscience, he team-teaches a course that covers the principles of neuroscience. In 1998, he received the Outstanding Graduate Teaching Award from the University.
