Mehari Gebreyohanns, M.D.
My research focuses on addressing the disparity in neurological care with emphasis on stroke globally and the Sub-Saharan Africa region in particular. The region carries a disproportionate burden of Non-Communicable Diseases, of which stroke is the leading cause of disability (see the BORNE initiative). In addition to my work in Global Neurology and Telemedicine, I am involved in several trials with a main focus on secondary prevention of strokes.
Mark Johnson, M.D.
My research areas have included intracranial cerebral arteriosclerotic occlusive disease, secondary stroke prevention including cardioembolic, large vessel and small vessel disease. I have been involved in trials that address acute stroke care as well as the prevention of recurrent stroke in patients with mild stroke and transient ischemic attack. Further data acquirement in the care of stroke patients and the use of ultrasound in cerebrovascular disease is overall an aim for future research.
Erica Jones, M.D.
My research objective is identifying community level cerebrovascular risk factors to target for primary stroke prevention. My project uses geospatial mapping to model the role of social determinants of health and racial isolation in creating disparities in stroke risk and outcomes.
Ty Shang, M.D., Ph.D.
My research interest is to understand the inflammatory and infectious roles (such as varicella-zoster virus infection) in intracranial large vessel disease and small vessel disease. I am also interested in comprehending the hemodynamic and metabolic changes in rare stroke disorders (Moyamoya Disease, CADASIL, CARASIL, COL4A1 mutation, MELAS and amyloid angiitis). High-resolution MR vessel wall imaging, MR spectroscopy and perfusion images provide needed information in evaluating the vessel wall and brain pathology, and tissue perfusion condition. The overall goal is to provide potential new therapeutic targets for these cerebrovascular diseases by looking for questions.
