My research focuses on understanding neuro-glial-vascular and extracellular matrix breakdown and how neuroimmune changes can lead to long-term cognitive dysfunction in cerebrovascular disease.

Stroke doubles the risk of later cognitive decline and dementia, and up to a third of stroke patients will develop post-stroke cognitive decline within five years. This highlights post-stroke cognitive decline as a key and unaddressed component of vascular dementia.
Despite research showcasing the importance of innate and adaptive immunity in stroke, research on inflammation as a cause of post-stroke cognitive decline is limited. We propose that immune alterations in the acute phase after stroke shape chronic maladaptive neuroimmune responses that compromise long-term structural and functional brain integrity, and contribute to post-stroke cognitive decline.
