Current and Past T32 Trainees

​​​​​​​​​Current Postdoctoral Fellows

​​Tiana Cowan, PhD

Dr. Tiana Cowan is a clinical speech-language pathologist and postdoctoral fellow in the Human Auditory Development Lab under the direction of Dr. Lori Leibold. Dr. Cowan completed her Master of Arts in Communication Sciences and Disorders at the University of Houston where she completed a thesis evaluating the diagnostic accuracy of two language sample measures. Dr. Cowan completed her doctoral training at Pennsylvania State University in Communication Sciences and Disorders and Language Science. Her dissertation explored how the semantic similarity between replacement errors and target words predicts lexical knowledge in Spanish/English bilingual adults. Dr. Cowan's research interests include bilingual sentence processing, clinical language assessment practices, and implementation science. Her interests also include understanding how language influences speech recognition in adverse listening condit​ions across the lifespan. Her short-term aims are to determine the time-course of adaptation to talker variability for monolingual and bilingual children and to identify factors that mediate age effects in adaptation.

​​Brittany T. Williams, PhD

Dr. Brittany T. Williams is a postdoctoral fellow in the Spatial Hearing Laboratory directed by Dr. G. Christopher Stecker. She completed her M.A. in Psychology at the State University of New York at New Paltz where she first investigated speech perception in complex listening situations. Dr. Williams earned her Ph.D. in Communication Sciences & Disorders and Language Science at the Pennsylvania State University where her research focused on the effect adverse listening conditions (e.g., background noise and differing spatial locations) have on speech perception. Broadly, she aims to explore how listeners are efficient and resilient in perceiving speech despite variability in the acoustic signal. Her research interests include speech perception, audiovisual speech perception, psycholinguistics, psychoacoustics, and hearing.

Past Postdoctoral Fellows

​​​Aryn Kamerer, PhD​

Aryn Kamerer is an Assistant Professor in the Communication Disorders and Deaf Education Department at Utah State University, and Director of the Hearing Health and Physiology Lab. Aryn completed her PhD in Audiology at the University of Kansas and a Postdoctoral Fellowship at Boys Town under the mentorship of Daniel Rasetshwane and Stephen Neely. The goal of Aryn's research is to develop clinical tools to diagnose auditory pathologies and understand how cochlear pathologies intersect with cognitive and psychosocial aspects of hearing.
