Researchers

Thomas Campbell, PhD [email protected]

Campbell is the Sara T. Martineau Professor in Communication Disorders in the School of Behavioral and Brain Sciences. He holds the Ludwig Michael Executive Directorship of the Callier Center for Communication Disorders. His research interests focus on early predictors of speech and language disorders in children as well as the identification of speech-motor and environmental variables that are associated with the recovery of communication skills after acquired neurological injury in childhood.

Holle Carey

Carey is the clinical research coordinator, for Vulintus, a company collaborating with Ctech to develop a software system that provides visual feedback of tongue movement.   Currently her research is aimed at determining if providing visual feedback of the tongue during speech therapy can be used to promote long-term gains in speech production.

Christine Dollaghan, PhD [email protected]

Dollaghan studies the nature, identification and outcomes of language and other communication disorders in young children, including children with specific language impairment and children recovering from traumatic brain injury. Her interests also include evidence-based practice and clinical decision-making. Current work focuses on the potential of non-invasive, non-volitional methods for quantifying language processing demands and learning rates in difficult-to-test groups, including young children.

Eric Farrar, MFA [email protected]

Farrar is an assistant professor in the Arts and Technology program in the School of Arts and Humanities. His professional experience is in 3D animation for feature films with a specialization in character rigging, creating internal structures and control systems that allow virtual 3D models to be animated. His research interests range from the use of computer imagery for scientific visualization to the cognitive processes of integrating music and animation.

Jordan R. Green, PhD [email protected]

Green is a professor in the Department of Communication Sciences and Disorders, Institute of Health Professions, Massachusetts General Hospital (MGH), Boston, MA. His research focuses on normal and disordered speech production, including motor speech impairment (e.g., due to amyotrophic lateral sclerosis), speech motor learning, speech development, and early chewing development.

John Hansen, PhD [email protected]

Hansen is associate dean for research for the Erik Jonsson School of Engineering and Computer Science and Distinguished Chair in Telecommunications. His research interests span the areas of digital speech processing, analysis and modeling of speech and speaker traits, speech pathology and voice assessment, speech enhancement and feature estimation in noise. His current emphasis is on robust recognition and training methods for spoken document retrieval and recognition in accent, noise, stress, and Lombard effect, and speech-feature enhancement in hands-free environments for human-computer interaction.

William Katz, PhD [email protected]

Katz is a professor of communication sciences and disorders. He studies language and the brain, including speech and language breakdown in adult aphasia and apraxia. He has researched coarticulation, child speech production and cue-trading relations at the prosody/syntax interface. His recent work focuses on the role of visual feedback in speech production, including applications for adult neurogenic patients and second language acquisition.

Michael Kilgard, PhD [email protected]

Kilgard is a professor in the School of Behavioral and Brain Sciences. His research focuses on understanding how experience rewires the brain. He is particularly interested in how experience with speech sounds alters the brain. Understanding how it adapts to new situations could help in developing new treatments for disorders such as tinnitus, autism and stroke.

Jeffrey Martin, PhD [email protected]

Martin is a clinical assistant professor and head of clinical audiology at the Callier Center. He has conducted research on the central mechanisms in hearing. Clinical applications of his research revolve around evaluation of individuals suspected of having auditory perceptual problems linked to the central nervous system, conditions known as auditory processing disorders.

Jenny McGlothlin, MS [email protected]

jenny-mcglothlin McGlothlin has a master’s degree in speech-language pathology and has worked as a speech therapist and clinical supervisor for the last 12 years. Her clinical work focuses on evaluation and treatment of children with feeding and speech disorders, specifically those disorders with a motor component. Research interests include differential diagnosis of motor speech disorders in children, as well as development of innovative diagnostic and treatment methods.

Balakrishnan Prabhakaran, PhD [email protected]

Prabhakaran is a professor of computer science, specializing in multimedia systems. He is focusing on video and health-care data analytics; streaming of 3D video, animations, and deformable 3D models; content protection and authentication of multimedia objects; quality of service (QoS) guarantees for streaming multimedia data in wireless ad hoc and mesh networks; and collaborative virtual environments. In the past, he has worked on multimedia databases, authoring and presentation, resource management and scalable web-based multimedia presentation servers.

Robert Rennaker, PhD [email protected]

An associate professor in neural engineering, Rennaker is involved in development of neural interface systems. His other research focus is systems level neuroscience. Additional interests include auditory neuroscience, plasticity and attention. He is acting director of the Texas Biomedical Device Center at UT Dallas.

Abhijeet Sangwan, PhD [email protected]

Sangwan received his PhD in electrical engineering from The University of Texas at Dallas in 2009. His research interests include automatic speech recognition, language recognition, accent analysis and robust speech signal processing. He is particularly interested in applications of speech and language technology in automatic assessment of spoken language, and speech analysis of long duration audio recordings.

Anusha Thomas, PhD [email protected]

Thomas is currently involved in measuring articulatory movements during speaking tasks in typical and disordered. Having research interest in measuring speech motor performance, her work includes examining mouth movements in early infant vocalizations and word learning in childhood apraxia.

Jun Wang, PhD [email protected]

Wang is an Assistant Professor of Biomedical Engineering and Communication Sciences and Disorders at UT Dallas. He earned his PhD degree in computer science with a specialty on speech production from the University of Nebraska-Lincoln in December 2011. He was a post-doctoral research associate at the Neurogenic Communication Disorders Consortium, University of Nebraska-Lincoln and University of Nebraska Medical Center, before he joined UT Dallas as a Research Scientist in Fall 2012. His research focuses on silent speech recognition/interface, normal and disordered speech production/recognition, and articulation-to-speech synthesis.
