  • Tomoki Hashimoto, MD

    Professor, Neuro-anesthesiology and Neurobiology

    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.
