Title: Inflammation and delayed cognitive dysfunction after stroke

The goal of this project is to investigate if chronic inflammation after stroke is one cause of post stroke dementia, a sub-category of vascular dementia, the second most common form of dementia in the US.

Title: Does increased TGF-b signaling in the elderly increase astrogliosis and impair functional recovery following stroke?

The goal of this project was to understand how aging affects astrogliosis and TGF-b signaling after stroke to help develop treatments that are tailored to elderly patients.
