Ashley Stokes, PhD, is an assistant professor of imaging research in the Keller Center for Imaging Innovation at Barrow Neurological Institute.
Dr. Stokes’ expertise includes the development and analysis of advanced neuroimaging methods for neurological diseases, including Alzheimer’s disease, multiple sclerosis, brain tumors, and Parkinson’s disease. She specifically focuses on multi-parametric imaging and multi-scale perfusion imaging methods. She is a member of the Arizona Alzheimer’s Consortium and the International Society for Magnetic Resonance in Medicine.
Dr. Stokes earned her doctorate degree in chemistry at Duke University in Durham, North Carolina. She completed a postdoctoral research fellowship at the Vanderbilt University Institute of Imaging Science.
Dr. Stokes’ research focuses on developing, validating, and translating advanced magnetic resonance image acquisition and analysis methods to noninvasively assess neurological diseases and disorders. She has applied these advanced imaging methods to probe key neuropathological changes in Alzheimer’s disease and other memory disorders, multiple sclerosis, and brain tumors.
