Dr. Argye Hillis is a professor of Neurology, with joint faculty appointments in Physical Medicine and Rehabilitation and in Cognitive Science.
Prior to medical training and neurology residency, Dr. Hillis worked as a speech-language pathologist, and conducted clinical research focusing on understanding and treating aphasia and hemispatial neglect. She has brought these areas of experience to impact on her clinical research in neurology, which involves cognitive and neuroimaging studies of aphasia and hemispatial neglect due to acute stroke and focal dementias. She has published extensively on these topics in journals and textbooks.
Dr. Hillis is Associate Editor of Stroke and has served as Associate editor of Brain, Annals of Neurology, Aphasiology, American Journal of Speech-Language Pathology, Neurocase, Cognitive Neuropsychology, and Language and Cognitive Processes and served as co-Editor and Chief of Behavioral Neurology.
Dr. Hillis serves as the Executive Vice Chair of the Department of Neurology and the Director of the Cerebrovascular Division of Neurology at Johns Hopkins.

Research & Publications
Following a stroke, an individual may experience speech, language, cognitive, or emotional problems. Dr. Hillis’ current research aims to improve the understanding of how language and other cognitive functions are represented and carried out in the brain, how they recover after injury, and how understanding these processes can contribute to evaluation and treatment of stroke and dementia. Specifically, current research studies include the following:
- Stroke Cognitive Outcome and Recovery (SCORE)
- Language Recovery After Stroke
- Cognitive Deficits and Recovery after Right Hemisphere Stroke
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 functions recover after stroke. Her other avenue of research involves novel treatment studies and longitudinal imaging and language studies of Primary Progressive Aphasia. She has published extensively on these topics in journals and textbooks.
