Interests
Cells in the cardiovascular system react to the changing mechanical stimuli. This affects their behaviour and can trigger cardiovascular disease onset and progression. We are studying cellular mechanosensing in cardiomyocytes and vascular smooth muscle cells, in 2D and 3D in vitro models and using tools to apply or measure forces (AFM, nanoindentation, nanopillars, pressure stimulation), as well as super-resolution or high content imaging and automated image analysis. This allows us to dissect cellular pathways of mechanosignalling and identify novel therapeutic targets, or to develop improved drug testing platforms.Publications
