Our Mission:

The goal of our research is to understand the molecular mechanisms of how neural and vascular networks are coordinately developed, communicated, and evolve to work in concert during normal and disease states.

Experimental Approaches:

Understanding neurovascular interactions is a research area that bridges the fields of neuroscience and vascular biology. Both the anatomical and functional aspects of neurovascular interactions are best seen under in vivo settings (for example, our research has been conducted in the retina, basal ganglia system, and cortex), therefore the main approach we use in the lab is mouse genetics. Specifically, this methodology allows us to simultaneously observe both systems endogenously and use genetic manipulations to perturb one system and observe the resultant consequences in the other. To identify and characterize molecular signals underlying neurovascular interactions, we have also developed a variety of in vitro assays, screening strategies, and computational models. We then transfer the findings from these in vitro techniques back to the in vivo system for validation. We aim to understand the neurovascular interactions from a molecular level to a systems level.

Central questions

Neurovascular biology is a relatively young field and very little is currently known. In order to elucidate the functional aspects of neurovascular interactions, such as the mechanisms underlying the coupling between neural activity and vascular dynamics or BBB formation and tightness, we must first understand and characterize the anatomical aspects of the neurovascular interactions. These basic characterizations and molecular identifications will provide important tools and premise for functional studies. Therefore my lab’s past and current research can be divided into two general directions- the mechanisms underlying the anatomical aspect of the neurovascular interactions, and the functional aspect of the neurovascular interactions.

(1) What are the molecular mechanisms underlying the establishment of neurovascular congruency?

(2) How do common guidance cues and their receptors function in wiring neural circuitry and shaping vascular topology?

  (3)What are the mechanisms underlying the cross-talk between neural activity and vascular dynamics?

(4) What are the molecular mechanisms governing the formation of a functional blood brain barrier (BBB)?
