The major focus of our lab is on the interplay between vascular cells and the extracellular matrix in blood vessel development and disease. Our lab applies developmental biology, genetic, biochemical, and omics approaches to uncover key insights into the morphogenesis and pathogenesis of the blood vessel wall.
