Johnson's research focuses on understanding how the human auditory system works in individuals with either normal or impaired auditory function. This work includes translational studies aimed at improving the identification and diagnosis of mild hearing loss in infants and young children. She is also investigating the impact of voluntary noise exposure on supra-threshold auditory function in individuals with normal behavioral thresholds.

These questions are addressed using a variety of techniques including otoacoustic emissions, auditory evoked potentials, and basic psychoacoustic and speech-perception tests. Work in Johnson's lab has been supported by grants from the American Academy of Audiology Foundation, the American Speech-Language-Hearing Foundation, and the National Institutes of Health–National Institute on Deafness and Other Communication Disorders.
