Maureen Shader, AuD, PhD

Principal Investigator

Maureen Shader is an Assistant Professor in the Department of Speech, Language, and Hearing Sciences and the director of the BRAiN Lab at Purdue University. She holds a bachelor’s degree in Communication Sciences and Disorders, a Doctor of Audiology (Au.D.) degree, and Ph.D. in Hearing and Speech Sciences. Dr. Shader completed a post-doctoral research fellowship as part of the Translational Hearing Research Group at the Bionics Institute of Australia where she developed a diagnostic test battery to address poor outcomes experienced by cochlear implant recipients. Her research investigates auditory perception and cortical processing in adults with cochlear implants. The goal of Dr. Shader’s research program is to better understand individual differences within the population of cochlear implant recipients and to improve post-implantation outcomes.

Eric Rodriguez, AuD

PhD Student, SLHS

Eric Rodriguez is a Ph.D. student in the Department of Speech, Language, and Hearing Sciences at Purdue University. He holds a bachelor’s degree in communication disorders from Texas State University and a clinical doctorate in audiology (Au.D.) from Purdue University. He completed a clinical + research externship at Boys Town National Research Hospital where he was able to evaluate and treat a wide range of populations, including cochlear implant recipients, dizziness patients, and difficult-to-test patients across the lifespan.
Eric’s research interest is largely influenced by his experiences as a clinician. He is interested in speech perception outcomes in cochlear implant recipients, particularly the factors that affect clinical performance. He assesses these factors using objective measures, such as functional near-infrared spectroscopy, and behavioral measures that are commonly used in a clinical setting, such as aided speech perception testing. Beyond academia, Eric enjoys hammocking, music, and finding creative ways to avoid Midwest winters.
