Research interests
The potential of mechanical circulatory support therapy has not yet been fully exploited due to adverse events caused by limited hemocompatibility of the devices. My main research focus is on rotodynamic blood pump design and the effects of pump flow on hemocompatibility - both in studying current clinically used cardiac assist devices and developing new devices for previously unaddressed patient populations, such as the Fontan population.
Techniques, methods & infrastructure
To understand the connection between pump design, flow and hemocompatibility related adverse events, I employ both in-silico (e.g. Computational Fluid Dynamics simulation) as well as in-vitro methods (e.g. performance testing in flow loop, blood testing).
