Research Interest

The goal of my research is the development of a complex, physiologically realistic finite element model of the human heart cycle, where a more comprehensive description could be found here.

My particular field of interests are

• Medical image processing
• Inverse Analysis
• Anisotropic material behaviour
• Computational solid mechanics of ventricles and heart valve
