Callier Postdoctoral Program

Every two years, since 2008, the Callier Postdoctoral Program admits two new Postdoctoral Fellows. The goal of the two-year program is to provide a vibrant, interactive community of researchers for the Postdocs to create an independent line of research that builds on or collaborates with one or more of the current Callier faculty. Because the program is funded through Callier’s Excellence in Education Fund Endowment, it provides the Postdocs with a great deal of flexibility in their research endeavors to advance knowledge and excellence in communication sciences and disorders.

Carlos Benítez Barrera, PhD

Current Postdoc

Carlos Benítez-Barrera earned his PhD in Hearing and Speech Sciences from Vanderbilt University in 2020 under the mentorship of Dr. Anne Marie Tharpe. He received his MA in Deaf Education from Fontbonne University and his BS in Psychology from Autónoma University of Madrid. His general research interest is the auditory and language development in typically and atypically developing children (e.g., children with hearing loss). Additionally, his research interests include the investigation of the relationship between the quality of the acoustic and language environments in which children grow up and their behavioral and neural language outcomes. His current research examines whether low language outcomes in children from disadvantaged households are related to the quality of their home communication environment. To fulfill his research goals, he implements a variety of techniques including EEG, behavioral measures and analyses of home recordings using LENA technology. The goal of his work is to understand to what extent experience modulates the development of auditory and language skills in children from diverse backgrounds.

Sonia Singh, PhD

Current Postdoc

Sonia Singh received a PhD in Psychology with a Cognitive Science concentration from Georgia State University. Her background involves the indexing of sequence learning abilities in individuals with and without reading impairments. Her current interests include understanding the roles of both the auditory and the motor system during speech production in children and adults. To further advance these lines of research, she is working with Dr. Lisa Goffman to investigate sequence learning capacity via speech, motor and cognitive mechanisms in those with and without language difficulties. Ultimately, this work will help understand how people use structure from their environment to perform common tasks such as learning to speak in a new language, make a series of automatic hand movements or how to read and spell correctly.
