Research interests

Cell-cell adhesion within the context of vascular tissue has been my major scientific interest in the past years. I identified several signaling cascades that target the central component of endothelial cell-cell adhesions, VE-cadherin, and thereby control vascular integrity, angiogenesis and leukocyte extravasation. To shift my focus to more translational research I decided to broaden my scientific scope to cell-cell adhesion in relation to cancer, particularly on interactions within the bone marrow microenvironment, comprising endothelial cells and mesenchymal stromal cells (MSC). I’m currently studying the cross-talk between MSC and tumor cells in bone marrow of patients with neuroblastoma.
