Contact Information

Research in Communication Sciences and Disorders

Our faculty members welcome undergraduate students into their labs as there are many opportunities for you to participate in ongoing research projects. Learn more about what each lab does and reach out to the contact for the one that interests you. Feel free to explore all the options as our faculty members have diverse interests.


Auditory Research Laboratory

Principal Investigator: Su-Hyun Jin, Ph.D.

The projects in the Auditory Research laboratory focus on

  • speech perception of hearing impaired listeners,
  • the effect of age on auditory processing and
  • speech production and perception of bilingual speakers.

These projects are oriented toward both basic and clinical research. 

Aphasia Research and Treatment Lab (ARTlab)

Principal Investigator: Maya Henry, PhD, CCC-SLP

Research in the lab is directed at improving our understanding of how the brain supports speech and language processes and how targeted treatment programs may improve communication impairments caused by stroke or neurodegenerative disease. The lab utilizes current approaches in cognitive neuroscience, neuroimaging, and cognitive rehabilitation to address these issues.

Brain Development Laboratory

Principal Investigator: James R. Booth, Ph.D.

Our mission is understanding disabilities in developing brains. We hope that our research will aid in the identification, diagnosis and treatment of children with disabilities.

Dr. Jennifer and Emanuel Bodner Developmental Stuttering Laboratory

Principal Investigator: Courtney Byrd, Ph.D.

Our mission is to help persons who stutter, family members of persons who stutter, and professionals who work with persons who stutter in the community through the provision and sharing of evidence based practices, the implementation of cutting edge clinical training methodologies, and the completion of innovative research with specific focus on translating theory to clinical practice.  

Communication in Adults Research Laboratory

Principal Investigator: Thomas Marquardt, Ph.D.

The primary goal is to understand acquired language disorders in adults. The current projects in the CAR Lab focus mainly on traumatic brain damage.

Hearing Function Laboratory 

Principal Investigator: Craig Champlin, Ph.D.

The aim of the Hearing Function Lab is to understand the workings of typical and atypical hearing systems. By understanding the underlying mechanisms of such systems, we are able to devise more sensitive tests used to characterize and track changes in hearing function over time.

Human Abilities in Bilingual Language Acquisition (HABLA) Laboratory

Principal Investigators: Lisa Bedore, Ph.D. and Elizabeth Peña, Ph.D.

The focus of the work at the HABLA lab is understanding how bilinguals organize and access their two language systems in an attempt to understand the nature of language breakdowns associated to language impairment.

Michael and Tami Lang Stuttering Institute

Principal Investigator: Courtney Byrd, Ph.D.

The mission of the Michael and Tami Lang Stuttering Institute is to help persons who stutter, their families, and their clinicians through the provision and sharing of evidence based practices, the implementation of cutting edge clinical training methodologies, and the completion of innovative research with specific focus on translating theory to practice.

Language Learning and Bilingualism Laboratory

Principal Investigator: Li Sheng, Ph.D.

The mission of the Language Learning and Bilingualism Lab is to understand how individual difference impact language and, specifically, vocabulary learning outcomes. Through these investigations, researchers aim to better understand the contribution of both learner-internal and learner-external factors to language development.

Chandra Laboratory

Principal Investigator: Bharath Chandrasekaran, Ph.D.

In the SoundBrain lab, researchers study the sensory and cognitive processes that underlie speech and music perception. Using functional magnetic resonance imaging (fMRI), event-related potentials (ERPs), brainstem electrophysiology and behavioral methods, they study the representation of speech and music in the human brain, and how these representations are modified by listening experiences.

Speech Production-Perception Laboratory

Principal Investigator: Barbara Davis, Ph.D.

The mission of the Speech Production Lab is to understand speech production characteristics in languages and acquisition in young children, in typical developmental circumstances and in circumstances where there is delay or disorder in achievement of expected developmental milestones. 

Speech Psychophysics Laboratory

Principal Investigator: Chang Liu, Ph.D.

The lab focuses on auditory processing of speech and non-speech sounds in a broad range of listeners including

  • native and non-native English listeners,
  • listeners with hearing impairment, and
  • children with typical development and speech disorders.

We are also interested in

  • speech acoustics for native and non-native speakers,
  • speech technology for speech enhancement, and
  • computational models for speech recognition.
