Ellie Tzima

Ellie Tzima is Professor of Cardiovascular Biology and Wellcome Trust Senior Fellow at the University of Oxford's Radcliffe Department of Medicine, leading the Tzima Mechanotransduction Group. Her pioneering research investigates how endothelial cells decode hemodynamic forces into biochemical signals governing vascular health and disease, with major implications for understanding atherosclerosis and heart failure.

Her work centers on endothelial mechanosensing mechanisms, particularly how laminar versus disturbed blood flow patterns regulate inflammatory pathways and vascular remodeling. Key discoveries include identifying plexin D1 and JCAD as critical mechanotransducers, and elucidating novel endothelial-cardiomyocyte communication pathways essential for cardiac development. The laboratory employs multidisciplinary approaches spanning bioengineering, magnetic tweezers, molecular biology, and transgenic animal models to dissect force-sensing mechanisms at cellular and molecular levels.

Analysis of her recent publications reveals strong thematic continuity in cardiovascular mechanobiology, with increasing focus on proteostasis regulation, ribosomal adaptation to mechanical stress, and endothelial-to-mesenchymal transition pathways. Her work demonstrates how mechanical forces directly modulate protein translation machinery and inflammatory responses, bridging biomechanics with molecular pathophysiology in vascular disease contexts.

• Wellcome Trust Senior Fellow

Professor Tzima's research program integrates genetic mouse models, advanced imaging, RNA sequencing, and metabolomics to investigate intercellular communication in the heart and vascular system. Her laboratory maintains active collaborations with the Channon and Watkins labs on coronary artery disease genetics, with ongoing work focused on harnessing mechanotransduction pathways for novel anti-inflammatory therapeutics targeting cardiovascular disease.
