GRINN, SARAH

Assistant Professor

FACULTY

Biography

Dr. Sarah Grinn conducts clinically-translatable research in animals and humans that advances our understanding of susceptibility to peripheral and central auditory noise injury. Ongoing projects in the Grinn Hearing Lab aim to reduce the incidence of recreational and occupational noise-induced hearing loss by improving the prediction model of auditory safety. Dr. Grinn’s current research, awarded by the National Institutes of Health, analyzes the effects of external-ear mechanics on temporary auditory deficit following a virtual-reality music concert exposure. Dr. Grinn collaborates with The University of Texas Southwestern Medical Center, The University of Texas at Dallas, and Boystown National Research Hospital.
