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.

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.

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.

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.

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.
