Anne Smith, Ph.D.
Distinguished Professor of Speech, Language, & Hearing Sciences
Director, Neurophysiological Bases of Speech Production/Language and Motor Interactions
Co-Director, Purdue Stuttering Project
Phone: (765) 494-3799
Anne Smith is a neuroscientist who is interested in how the brain does the complicated task of producing speech. She is also particularly interested in what happens when the speech production system does not work, as is the case in stuttering. She has studied stuttering in adults, school-age children, and in preschoolers to find the factors that contribute to the onset and persistence of this problem.
Christine Weber, Ph.D., CCC-SLP
Professor of Speech, Language, & Hearing Sciences
Director, Neural Systems for Language Processing Lab
Co-Director, Purdue Stuttering Project
Chris Weber’s research program examines neurodevelopmental aspects of stuttering in preschool children. Her longitudinal studies examine behavioral and clinical measures coupled with measures of brain activity elicited for language processing. The aims for her research are to help identify factors that contribute to the development of stuttering and also to discover physiological and clinical predictors of persistence versus recovery of stuttering in preschool children.
Bridget Walsh, Ph.D. CCC-SLP, Research Scientist
Phone: (765) 496-0151
Bridget Walsh is a Research Scientist in the Department of Speech, Language, and Hearing Sciences at Purdue, and a co-investigator on the Purdue Stuttering Project. Speech production is seemingly effortless, yet it is a remarkably complex process. Dr. Walsh’s overarching interest is how the brain controls this quintessential human ability. She has researched how speech develops in young children, and how the disease mechanisms of disorders such as Parkinson’s disease and stuttering disrupt speech production. Currently she is studying the neural processes that mediate speech planning and production and, in parallel, discovering neurophysiological markers of stuttering using a non-invasive neuroimaging technology, fNIRS.
Barb Brown, M.S. CCC-SLP, Project Coordinator
Phone: (765) 496-6403
As a speech-language pathologist with many years of experience working with preschool children, I feel fortunate to have the opportunity to combine my clinical expertise with research on the development of stuttering in young children. The goal of this phase of the Purdue Stuttering Project is to develop clinical screening tools to identify children at risk for persistent stuttering, and my hope is that this will result in earlier and more effective intervention for these children.
Janna Berlin, Research Associate
Phone: (765) 494-3799
Janna earned her B.S. in Speech and Hearing Sciences at Purdue and has worked as a Research Associate for Professor Smith since 1993. She helps collect and analyze all physiological data connected with the Purdue Stuttering Project. She also teaches new students in the lab to do the same. When not seeing subjects in the lab she likes to walk her dog, Murphy, read and take camping trips to the western parts of the country.
Eileen Haebig, Ph.D. CCC-SLI
Eileen Haebig is a postdoctoral fellow in the Department of Speech, Language, and Hearing Sciences at Purdue University. She received her PhD in Communication Sciences and Disorders at the University of Wisconsin – Madison. As a clinical researcher and certified speech-language pathologist, she is interested in language learning in children with neurodevelopmental disorders. She studies language abilities in children with fragile X syndrome, autism spectrum disorders, and specific language impairment. Eileen uses a multi-level approach, using eye-tracking, behavioral methods, and event related brain potentials (ERP), to explore how children with atypical development process and learn language.
Evan Usler, Ph.D. Student
Evan Usler is a Ph.D. student in the Department of Speech, Language, & Hearing Sciences. He graduated from Boston University with a B.A. in International Relations and from the University of Rhode Island with graduate degrees in Information Studies and Public Administration. Interested in the neural subsystems of speech and language, how these systems develop, and how they interact with cognitive and emotional processes, he focuses on stuttering and related neurodevelopmental speech-language disorders. Outside of the lab, Evan enjoys drinking coffee, playing football, and watching holiday-themed Hallmark movies.
Ranjini Mohan, Ph.D. Student
Ranjini is a PhD student in the Dept. of Speech Language and Hearing Science at Purdue University and has been a member of the Neural Systems for Language Development Lab since 2011. She graduated with a Masters degree from Mysore University, India. Her research interests are in understanding the neurophysiological basis of language and cognitive processing in older adults. In her free time, Ranjini enjoys singing and dancing and is an ardent animal lover.
Katie Lippitt, Research Assistant
Katie is a combined M.S/PhD student in the Department of Speech Language and Hearing Science. She graduated from University of Maryland, College Park with a B.A. in Hearing and Speech Sciences and Psychology. Her research interests include the neural underpinnings of normal dysfluencies, such as “um” and “uh”, and pathological dysfluencies, such as stuttering events. Outside of speech language pathology, Katie enjoys singing, baking and playing sports.
Anna received her BS in Speech, Language, and Hearing Sciences from Purdue University in 2013 and has been a research assistant since that time. She will begin her graduate work in the fall, also at Purdue University, with an interest in working with clinical populations. When not in the lab, she is happiest while metalsmithing, reading, and getting lost outdoors with her two pups and better half.
Kristin Lynch, Undergraduate Research Assistant
Kristin Lynch is a junior in Speech, Language, and Hearing Sciences with a minor in Psychology. Her research interests include how neurological planning and disorders affect speech in children, such as apraxia. She is also highly interested in how cerebral vascular accidents affect people’s speech, planning, motor skills, and how to prevent them.
Lindsay Rozynek, Undergraduate Research Assistant
Lindsay is a sophomore studying Speech, Language, and Hearing Sciences with a minor in Human Development and Family Studies. After spending her summer volunteering/observing at a therapy clinic, she found an interest in child communication disorders. She hopes to obtain her masters in speech-language pathology.
Emily Malek, Undergraduate Research Assistant
Emily Malek is a Sophomore in Biochemistry with a minor in Statistics. As part of a Statistics Living-Learning Community, she participates in Dr. Weber’s lab helping to process data and run statistics. In her spare time, Emily enjoys cooking, reading, watching movies and taking way too many pictures of her cats.
