Our Research

Dr. Nancy Hall is recognized for her expertise in fluency disorders. Her areas of research include the relationship between language and fluency in early language acquisition in both typically developing children and those with communication disorders. Dr. Hall served on the ASHA Joint Coordinating Committee on Evidence Based Practice, and is a past editor of Perspectives in Fluency and Fluency Disorders, the peer-reviewed publication of ASHA’s Special Interest Group in Fluency and Fluency Disorders.

Dr. Judy Walker’s research explores prosodic deficits in adults with right and left hemisphere brain injury. She is interested in the abilities of brain-damaged subjects to process and produce prosodic features that influence lexical access, syntactic parsing and the categorical assignment of questions and statements. Her research encompasses response time methodology and acoustic measurements of prosodic features.

Dr. Christopher Grindrod directs the Neurolinguistics and Aphasia Research Lab in the Department of Communication Sciences and Disorders at the University of Maine. His primary area of expertise is in studying acquired language disorders to better understand how language is processed by the brain. Among the patient populations he has worked with are individuals with aphasia, patients with right hemisphere brain damage, and individuals with Parkinson’s disease. His current research examines the effect of left- vs. right-brain damage on the ability to use lexical- and sentence-level context information to guide word processing. He has also recently begun studying the effects of aging on language comprehension. The ultimate goal of his research is to shed light on brain-language relationships which will lead to improved assessment and treatment of individuals with acquired language disorders or age-related cognitive decline.

Dr. Jennifer Seale’s research and clinical interests are focused on augmentative and alternative communication (AAC) science and practice. Dr. Seale has expertise providing AAC services to diverse client populations, including individuals with ALS, Cerebral Palsy, Locked-In Syndrome, Aphasia, TBI, RHD, Fragile X, Down Syndrome, and Autism. Her research aims to inform AAC service delivery and product design using human computer interaction, interaction analysis and mixed-methodology techniques. In addition to these interests, Dr. Seale is devoted to advocacy and public education around important social and systemic issues unique to the AAC community.
