Tomoki Hashimoto, MD
Tomoki Hashimoto, MD, is a professor of neuro-anesthesiology and neurobiology and the director of translational neurovascular research in the Barrow Aneurysm and AVM Research Center. He is board certified in anesthesiology by the American Board of Anesthesiology.
Dr. Hashimoto’s expertise includes clinical anesthesiology and vascular biology. He earned his medical degree from Gifu University School of Medicine in Japan. He received his residency training in anesthesia at Gifu University Hospital, Thomas Jefferson University Hospital in Philadelphia, and NewYork-Presbyterian/Columbia University Medical Center. He completed a clinical fellowship at NewYork-Presbyterian/Columbia Medical Center and a research fellowship at the University of California-San Francisco, both in neuro-anesthesia.
Dr. Hashimoto leads a program that focuses on the translational research of cerebrovascular diseases. His group studies the roles of inflammation and vascular remodeling in the pathophysiology of intracranial aneurysms and brain arteriovenous malformations. They are developing pharmacological therapies for the prevention of stroke caused by rupture of intracranial aneurysms and brain arteriovenous malformations.

Gregory Turner, PhD
Gregory Turner, PhD, is the preclinical imaging program manager in the Keller Center for Imaging Innovation at Barrow Neurological Institute. He oversees the operation of the Barrow-ASU Center for Preclinical Imaging.
Dr. Turner’s expertise includes biomedical engineering and imaging science. He is a member of the International Society for Magnetic Resonance in Medicine.
Dr. Turner received a master’s degree in electrical engineering from the University of Alabama and a master’s degree in biomedical engineering from the University of Alabama at Birmingham, where he also earned his doctorate in biomedical engineering. He completed a graduate research fellowship in the Department of Biomedical Engineering at the University of Alabama at Birmingham and a postdoctoral fellowship at the Vanderbilt University Institute of Imaging Science.
Dr. Turner’s research interests include developing and implementing imaging methods for studying a variety of disease models, including Alzheimer’s disease, inflammation, cancer, and spinal cord injury. He also has an interest and background in functional MRI and cardiac imaging.
Ashley Stokes, PhD
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.
