Research & Scholarship: 

Pre-clinical stroke research to understand: 1) the role of sex differences and menopause in neuro-inflammatory mechanisms of brain injury during ischemic stroke and reperfusion, and 2) the effect of co-morbid conditions preceding stroke, such as hypertension, to alter neuro-inflammatory responses and the evolution of brain injury after ischemic stroke.
