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.

Professor of Speech, Language, & Hearing Sciences

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.

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 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.

Bridget Walsh has studied speech motor control across the lifespan; in those with Parkinson’s disease, and most recently, in young children who stutter. She is interested in learning if physiological factors related to speech and language processes predict persistence versus recovery in young children who stutter. Her current research focus is on neural activation patterns during speech production using a non-invasive method of neuroimaging, Functional Near-Infrared Spectroscopy.

Phone: (765)494-3819

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.

Allison Hilger is a Master’s student in the Speech, Language, and Hearing Science Department with the intent of continuing her studies and earning her Ph.D. Allison earned her B.S. in Speech and Hearing Science from the University of Illinois. Her research interests are in the epigenetics of communication disorders, such as stuttering, particularly looking at the motoric abilities of people who stutter. While working on her undergraduate degree, Allison’s research work involved looking at motor stability in second language acquisition of America Sign Language. In her free time, Allison enjoys playing the piano, spending time with her nephews, and reading The Hobbit.

Katie is Master’s student in the Speech, Language, and Hearing Sciences department. She earned her B.S. from the State University of New York at Geneseo where she developed an interest in the cognitive neuroscience of stuttering. She is excited to pursue this interest in her research at Purdue. In addition to her interest in cognitive neuroscience, she is fascinated by how perceptions of speech and language disability vary culturally and historically. Outside of the field, Katie enjoys astronomy, entomology, and reading Cheryl Strayed.

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.
