Research interests

My research focuses on device-based treatment options for unmet medical needs in cardiovascular medicine. On the one hand our group develops innovative systems for mechanical circulatory support, one the other hand we optimize the patient-device interaction to promote preservation or even recovery of cardiovascular function.

Techniques, methods & infrastructure

Our team covers the entire R&D pipeline for complex medical devices, from in-silico methods (CAD, CFD, lumped parameter models, virtual fitting), in-vitro experiments (hybrid test benches, animal/human blood experiments), ex-vivo approaches (isolated beating heart model) to in-vivo animal models (acute and chronic large animal experiments) and clinical studies.
