Aphasia

Dr. Argye Elizabeth Hillis is a Professor of Neurology, with joint faculty appointments in Physical Medicine and Rehabilitation and in Cognitive Science at Johns Hopkins University. Dr. Hillis serves as the Executive Vice Chair of the Department of Neurology, and Director of the Cerebrovascular Division of Neurology. Dr. Hillis is Deputy Editor of Stroke and Associate Editor of Aphasiology and has served as Co-Editor-in Chief of Behavioural Neurology, Associate Editor of Brain, Annals of Neurology, American Journal of Speech-Language Pathology, Cognitive Neuropsychology, and Language and Cognitive Processes. She also currently serves on the editorial boards of Annals of Neurology and International Journal of Stroke. Dr. Hillis was the 2003 recipient of the Derek Denny Brown Neurological Scholar Award from the American Neurological Association and the Norman Geschwind Award in Behavioral Neurology from the American Academy of Neurology. Her current research is supported by the National Institutes of Health (NINDS and NIDCD). She is on the Board of Directors of the World Stroke Organization.Dr. Hillis' current research combines longitudinal task-related and task-free functional imaging and structural imaging from the acute stage of stroke through the first year of recovery, with detailed cognitive and language assessments to improve our understanding how language and other cognitive and emotional functions recover after stroke. She is investigating the most effective timing of neuromodulatory treatments, such as transcranial direct current stimulation and medications, to augment behavioral therapies after stroke. Her other avenue of research involves novel treatment studies and longitudinal imaging and language studies of Primary Progressive Aphasia. (PPA). She is currently studying three forms of treatment of PPA: language therapy and transcranial Direct Current Stimulation (in studies funded by NIDCD) and neurofeedback with aphasia therapy. Dr. Fridriksson is a Professor and Interim Vice President for Research, University of South Carolina. He research focuses on the rehabilitation of aphasia and the neurobiology of speech and language processing. Dr. Fridriksson has a long history of external research funding (exceeding $40M), primarily from the National Institutes of Health (NIH). He also leads UofSC’s Center for the Study of Aphasia Recovery with collaborators at Johns Hopkins, the University of California-Irvine, and Emory University.A USC Health Science Distinguished Professor and Co-Director of the McCausland Center for Brain Imaging since 2012, Dr. Fridriksson’s prior teaching experience includes various UofSC professorial positions of increasing responsibility, 2001-2021; and Research Fellow, University of Arizona, 1998-2001.Dr. Fridriksson earned his Ph.D. in Speech and Hearing Sciences from the University of Arizona and both his M.A. in Speech-Language Pathology and B.A. in Communicative Disorders from University of Central Florida.
