Description of Research Expertise:

Clinical/translational research focuses on peripheral nerve repair and regeneration, as well as a variety of projects in cerebrovascular surgery. Collaborative research includes evaluation of safety and efficacy of xenon-CT for cerebral blood flow monitoring in subarachnoid hemorrhage and trauma; evaluation of a noninvasive near-infrared spectroscopy device for detection of intracerebral hematomas; evaluation of brain oxygen tension monitoring in subarachnoid hemorrhage; arterial spin-labelling MR in AVM shunt visualization; MRI evaluation of carotid plaques and hemispheric blood flow before and after carotid endarterectomy; cost-effectiveness analysis of imaging in carotid endarterectomy and cerebral aneurysm repair; clinical outcomes for surgical treatment of patients with intractable occipital neuralgia.
