My research aims to better understand blood flow hemodynamics in arteries, using numerical modeling. I particularly focus on coupled 1D-0D models, which produce efficient wave propagation results, while presenting a limited complexity and parametrisation.

My PhD thesis focused on the particular application of bypass surgeries in lower-limb arteries. Using a 1D-0D numerical model parametrised with patient-specific in-vivo data, I improved the understanding of waves in the pathological arteries and graft.

Using simple 0D models of the arterio-venous circulation and the heart, I studied the feasability of a new type of VAD for the particular Fontan heart pathology. Once optimised, I tested the new device on an in-vitro bench.

My current work studies the propagation of arterial waves in patients suffering from hypertension. Using numerical modeling together with experimental in-vitro studies, we aim at developing a diagnostic tool for hypertensive patients.
