My research focuses on several interrelated areas that affect stroke and dementia outcomes. More specifically I am interested in the following areas: Outcome research related to specific interventions affecting the vascular endothelium in stroke and Alzheimer’s disease; health care disparities relating to race, age and gender in stroke and dementia; optimal management and effects on primary and secondary stroke prevention; genetic markers in cryptogenic stroke to aid in sub-classification and management; clinical trials in acute stroke and stroke prevention; data mining in sleep related disorders; and stroke.
