Biography

Elizabeth Strickland, Ph.D., CCC-A, is the Director of the Psychoacoustics Lab. She completed her M.S. in Audiology at Purdue in 1994.  She received her Ph.D. from the University of Minnesota (Psychology)  in 1994, and did a post-doctoral fellowship at the University of Florida (Psychology) from 1994-1995.  She joined the faculty at Purdue University in 1995.  Dr. Strickland’s research is on behavioral measures of hearing, particularly those that may reflect the processing of the peripheral auditory system. She has particularly focused on measurements that may reflect adjustment of the ear to sound in normal hearing, and how this may be affected by mild cochlear hearing impairment.  She currently teaches graduate courses in psychoacoustics and in hearing conservation.  She is the Graduate Chair of SLHS.  She is also the Director of the SLHS NIH Training Grant
