Research Interests

Our goal is to understand the cellular and molecular mechanisms that regulate blood-brain barrier (BBB) function during health and disease. The BBB is a specialized structure formed by the blood vessels in the central nervous system (CNS) that is critical for proper brain function as well as protecting the brain from injury and disease. Breakdown of the BBB occurs during stroke, edema, brain trauma, and multiple sclerosis and is a major component of the symptoms and progression of these diseases. We use a combination of cellular, molecular and genetic approaches to understand the mechanisms of BBB formation and function. We are interested in asking:

  1. How is the BBB formed during development?
  2. How does the BBB interact with neuronal circuitry to regulate brain function and behavior?
  3. What are the molecular mechanisms that lead to BBB disruption during neurological disease?

The goal of our work is to elucidate these mechanisms, such that we will be able to develop therapeutics to rebuild the barrier to treat neurological diseases, as well as methods to bypass the barrier to deliver drugs to the CNS.
