Andrea Warner Czyz

Andrea Warner-Czyz, PhD, CCC-A

Dr. Warner-Czyz’s research focuses on how young children with severe to profound hearing loss who wear cochlear implants develop speech, language, hearing, and quality of life. She is most interested in exploring the variability in this population to see if we can identify children at risk for slower or poorer development of communication and life satisfaction skills.

Dr. Warner-Czyz earned a BA in Speech and Hearing Science at the University of Illinois, a MA in Audiology at the University of Florida, a PhD at the University of Texas at Austin, and a MS in Clinical Sciences at The University of Texas Southwestern Medical Center.

Dr. Warner-Czyz enjoys exercising, biking, and reading. She also loves sports, especially football (Go Gators!) and gymnastics.
