Blood and lymphatic vessels are highly specialized and adapt their identities to the organs they serve. In our lab, we study how these vessels communicate with surrounding tissues, including immune cells, hematopoietic cells, neurons, and stromal cells, to guide vascular development, support organ function, and enable regeneration after injury. Our work spans diverse contexts, from vascular regulation of hematopoietic niches to the formation and function of cardiac lymphatic networks, revealing how vascular communication shapes tissue homeostasis and repair.
