Shawn Goodman, Ph.D., CCC-A

Associate Professor

Shawn Goodman CV

Research focus
As a researcher, Shawn Goodman's training is in auditory physiology, neuroscience, and acoustics. As an audiologist, he also has strong clinical interests, with a passion for understanding the mechanics of the peripheral auditory system and how to apply that understanding in clinically useful ways, with expertise in areas of cochlear mechanics, particularly with otoacoustic emissions, in both animal models and human participants. His audiology background and work with human participants is a strength for linking the results from animal models to issues important for clinical application in humans. Over the course of 15 years, he has built and refined a custom software/hardware system for making physiological measurements, particularly from the auditory periphery. His software and hardware system, Auditory Research Lab audio software (ARLas), has been successfully used for data collection in many laboratories across the country, and it includes capabilities for calibration, simultaneous multi-channel output and multi-channel recording, and file management.
