Research Impact

My research focuses on community-based models to support those who are living with stroke as a chronic condition. I am focused on identifying inflammatory mechanisms in the microcirculation of the brain during reperfusion after ischemic stroke.

Research Interests

Stroke: 1. Mechanisms of inflammation in the cerebral microcirculation during reperfusion after stroke2. Stroke Systems of Care
