Welcome to the Kahn Laboratory

The Kahn Lab is interested in signaling pathways at the intersection of cardiovascular development and disease.  We study lymphatic and blood vascular pathways and the interactions between blood cells and vascular endothelium.  Our focus is on human cardiovascular diseases such as venous thrombosis, cerebral cavernous malformation, and heart valve disease.

We combine complex mouse genetics with state-of-the-art biochemical and molecular approaches to understand the function of these pathways during normal development and in postnatal disease models. We have collaborations across Penn, CHOP, and many other academic institutions.











The Kahn Lab is committed to promoting a diverse and inclusive environment for individuals of all backgrounds, particularly those who are underrepresented in science and medicine. Our lab is committed to social justice and anti-racism, and we welcome all aspiring scientists to join our lab.

We are currently accepting graduate students and applications for postdoctoral research fellows! Please email Dr. Kahn at if interested in joining the lab.
