  • Our vision

    Our research seeks to advance our understanding of cerebrovascular disease and to develop new minimally invasive treatments for these diseases. We study ischemic and hemorrhagic stroke, cerebral aneurysms, delayed cerebral ischemia, cerebral arteriovenous malformations (AVMs), dural arteriovenous fistulae, and other vascular diseases of the brain. We use state-of-the-art neuroimaging techniques to non-invasively study these diseases, and we are developing future endovascular technologies to advance neurointerventional surgery.

    Basic and Translational Science Research

    From bench top...

    Our basic and translational scientific team is working to advance our understanding of cerebrovascular development and patterning, the genetic basis of cerebrovascular malformation and aneurysm pathogenesis, and cellular adaption to cerebral ischemia. Our current knowledge about cerebrovascular development in humans is meager and limits our ability to develop new, molecularly targeted treatments for ischemic and hemorrhagic strokes. New knowledge about cerebrovascular development could generate new, molecularly targeted treatments for ischemic and hemorrhagic strokes and transform clinical paradigms for these diseases.

    Clinical Research

    ...to bedside.

    Our clinical research team seeks to advance our understanding of ischemic and hemorrhagic stroke pathophysiology and improve the non-invasive imaging evaluation and endovascular treatment of these diseases. In addition, we are working to identify circulating biomarkers of acute and subacute cerebral ischemia to identify patients at risk of stroke before it happens.
