Experience Speech, Language, and Hearing Sciences at Moody

The lab primarily pursues two lines of research. One area of research investigates AAC interventions and their effectiveness in persons with chronic, severe aphasia and variables that influence outcomes. The second line of research focuses on understanding factors that influence symbol learning in persons with developmental disabilities, including autism. The lab is equipped with several speech generating devices, stand-alone apps and eye-tracking software programs.
Principal Investigator: Rajinder Koul, Ph.D.

The lab focuses on improving understanding of how the brain supports speech and language processes and how targeted treatment may improve impairments caused by stroke or neurodegenerative disease. Lab findings have resulted in more than 30 peer-reviewed publications.
Principal Investigator: Maya Henry, Ph.D., CCC-SLP

The research laboratory focuses on helping persons who stutter, family members of persons who stutter and professionals who work with persons who stutter. In addition to investigating the nature of stuttering, the lab also works to better understand effective treatment practices for children, teenagers and adults who stutter.
Principal Investigator: Courtney Byrd, Ph.D., CCC-SLP

Research is focused on cortical plasticity, or the brain’s ability to adapt to environmental changes.
Principal Investigator: Julia Campbell, Ph.D.

The lab and its 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 the work and research happen in schools.
Principal Investigator: Mary Beth Schmitt, Ph.D., CCC-SLP

The primary goal is to understand acquired language disorders in adults; current projects focus on traumatic brain damage. Dr. Thomas Marquardt, the principal investigator, has authored or co-authored three texts on communication disorders and more than 50 research articles.

Part of the NeuroComm Labs, the Hamilton Lab studies how the human brain processes speech sounds, and how natural sounds are represented in the human brain.
Principal Investigator: Liberty Hamilton, Ph.D.

The aim is to understand the workings of typical and atypical hearing systems, and thus devise tests to characterize and track hearing function over time.
Principal Investigator: Craig Champlin, Ph.D.

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. Pharyngeal high-resolution manometry, videofluoroscopy, EMG, respiratory measurements, and transcranial magnetic stimulation (TMS) are employed.
Principal Investigator: Corinne Jones, Ph.D., CCC-SLP

The lab explores evidence based interventions, such as parent-directed treatment, for children with autism spectrum disorders and other developmental delays.
Principal Investigator: Jesse Franco, Ph.D., CCC-SLP

The lab focuses on auditory processing of speech and non-speech sounds in a range of listeners, including: native and non-native English speakers, listeners with hearing impairment and children with typical development and speech disorders.
Principal Investigator: Chang Liu, Ph.D.

The lab focuses its research on 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.
Principal Investigator: Dr. Zoi Gkalitsiou

The lab studies neural processes, from inner ear to cortex, involved in speech perception in noise. Objective and behavioral techniques are employed to study relationships between neurophysiological function and perception. Research outcomes have clinical implications for diagnosing and treating individuals with speech-in-noise perception deficits.
Principal Investigator: Spencer Smith, Ph.D., Au.D.

The lab focuses its research to improve the diagnosis and treatment of neurogenic voice disorders, including vocal tremor. The vocal function of speakers with voice disorders, healthy speakers and professional voice users, including singers, is studied through a variety of methods, including endoscopy and electromyography.
Principal Investigator: Rosemary Lester-Smith, Ph.D., CCC-SLP
