Research in Speech, Language, and Hearing Sciences

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.

Augmentative and Alternative Communication Laboratory

Principal Investigator: Rajinder Koul, Ph.D.

The Augmentative and Alternative Communication Lab’s aim is to improve the efficacy of augmentative and alternative communication intervention for persons with severe speech and language impairment as a result of developmental and acquired conditions. We study the variables that influence the outcomes of such interventions, including symbol identification, the perception of synthetic speech, dynamic display configurations, and alternative access methods such as eye-tracking and brain-computer interface systems.

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.

Central Sensory Processes Lab

Principal Investigator: Julia Campbell, Ph.D.

Our research is focused on cortical plasticity, or the ability of the brain to adapt to changes in the environment.  Specifically, we are interested in how a typical brain with no sensory disorders might process various sensory input such as audition and vision over the lifespan, and how these cortical functions interact.

Children's Language, Literacy & Learning Lab (CL3 Lab)

Principal Investigator: Mary Beth Schmitt, Ph.D., CCC-SLP

Dr. Schmitt’s research focuses on identifying active ingredients of language therapy that lead to improved language abilities for preschool and school-age children with language disorders. Much of her work happens in the field (i.e., in the schools). Currently, Dr. Schmitt and her team are investigating the role of children’s behavior regulation, peer effects, and service delivery models as they relate to children’s language development funded through NIH and local funding agencies.

Hamilton Lab

Principal Investigator: Liberty Hamilton, Ph.D.

The Hamilton lab investigates how the human brain processes speech sounds using intracranial electrocorticography (ECoG) recordings from patients with intractable epilepsy who are undergoing surgery to treat their epilepsy.  We use a combination of electrophysiology, behavior, neuroimaging, and computational modeling to ask how different features of sounds are combined to form the words that we speak and hear, and how this changes during development.

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. The HABLA lab is no longer active on UT campus.

Jones Lab

Principal Investigator: Corinne Jones, Ph.D., CCC-SLP

The Jones Lab’s research goals are to better understand how the brain controls swallowing, how this changes in neurologic and neurodegenerative diseases, how to improve dysphagia evaluation, and to develop novel dysphagia rehabilitation paradigms. To do this she uses pharyngeal high-resolution manometry, videofluoroscopy, EMG, respiratory measurements, and transcranial magnetic stimulation (TMS).

Michael and Tami Lang Stuttering Institute

Principal Investigator: Courtney Byrd, Ph.D., CCC-SLP

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.

Multilingual Aphasia and Dementia Research Lab (MADRlab)

Principal Investigator: Stephanie Grasso, PhD., CCC-SLP

Research in the lab focuses on developing treatment approaches for bilingual adults with aphasia and neurodegenerative disorders. In addition, we are interested in better characterizing the manifestation of aphasia and neurodegenerative disorders in individuals from culturally and linguistically diverse backgrounds. Research in the lab also addresses bilingualism as a contributor to cognitive and neural reserve and utilizes neuroimaging to investigate variability in treatment responsiveness.

Skills Lab

Principal Investigator: Jesse Franco, Ph.D., CCC-SLP

Skills and Knowledge of Intervention for Language Learning Success (SKILLS) Lab explores evidence based interventions, such as parent-directed treatment, for children with Autism Spectrum Disorders and other Developmental Delays.

Sound Brain 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. The Sound Brain Laboratory is no longer active on UT campus.

Speech Disorders and Technology Lab

Principal Investigator: Jun Wang, Ph.D.

The lab is dedicated to develop assistive speech technologies including silent speech interfaces and to conduct basic speech science and disorders research on neurogenic motor speech disorders and neural processing for speech communication.

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.

Stuttering and Linguistic Processing Lab

Principal Investigator: Zoi Gkalitsiou, Ph.D., CCC-SLP

The Stuttering and Linguistic Processing Lab’s research includes the investigation of linguistic and cognitive factors that contribute to the development and maintenance of stuttering using eye-tracking methodology, the manifestation of stuttering in bilingual speakers, and the improvement of evidence-based practices in stuttering.

Texas Auditory Neuroscience Laboratory

Principal Investigator: Spencer Smith, Ph.D., Au.D.

Research in the Texas Auditory Neuroscience Lab focuses on neural processes, from inner ear to cortex, involved in speech perception in noise.  We employ objective (otoacoustic emission and electroencephalography) and behavioral techniques to study relationships between neurophysiological function and perception.  Ongoing work in our lab is currently funded by the National Institutes of Health.

UT Voice Lab

Principal Investigator: Rosemary Lester-Smith, Ph.D.

We study voice production in individuals with neurological disorders, healthy speakers, and singers to identify factors that improve or impair vocal control. Our interdisciplinary research aims to advance assessment and treatment of neurological voice disorders.
