I am a SNSF postdoctoral fellow in the High-Reynolds Number Fluid Flow group working with Professor Richard Kerswell. I finished my PhD studies in Biomedical Engineering at University of Bern in March 2020. My research lies at the overlap of cardiovascular engineering, fluid mechanics, numerical methods for computational fluid dynamics and high-performance computing. I am particularly interested in investigating and control of adverse blood flow events in the left heart, past the aortic valve and in the thoracic aorta, mainly those linked to turbulence.
