Research in Communication Sciences and Disorders
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.
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.
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.
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.
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.
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.
