The key interest of my laboratory is understanding how cells use their genome to integrate environmental and mechanical cues to coordinate tissue morphogenesis during development. We focus on the development of the blood and vascular systems, paradigmatic tissues where hemodynamics and genetic programs act in tandem to pattern the vascular tree and direct the formation of hematopoietic stem cells from hemogenic endothelium. We pursue these questions primarily in the zebrafish Danio rerio, a genetically tractable vertebrate model in which vascular function and forces can be preserved while experimental and live imaging approaches are conducted. At the VBRI, we leverage the collaborative environment and depth of hematology expertise to translate these findings into human and murine models, and take a keen interest in the scientific training and career development of our team. Ongoing projects in the lab aim to decipher the suite of molecular changes induced by hemodynamics in hemogenic endothelium that are responsible for the successful production of hematopoietic stem cells by the endothelial-to-hematopoietic transition.
