Primary Research:

The overall goal of the lab is to understand the role of the extracellular matrix, particularly the elastic fiber, in vascular development and disease such as aneurysms and hypertension. We utilize mouse models carrying disease-causing mutations or lacking extracellular matrix genes to study their role in elastic fiber assembly.
