By Birgit Baustädter - Biomechanical engineer Justyna Niestrawska investigates the mechanical behaviour of the aorta at TU Graz and represents it using mathematical formulas. And wins the German Aorta Prize while doing so. What has mechanical engineering got in common with the human body? Can you explain biological processes like the operations of a machine? The biomechanical engineer Justyna Niestrawska can answer these questions - straight out of her daily work. Her special field is continuum mechanics, in which the operations of the human body are described, modelled and simulated using mathematical equations. German with Polish roots, she originally studied mechanical engineering at RWTH Aachen and specialised in plastics technology. She began to be interested in medical engineering during her master's programme when she conducted research on heart valves. During a research stay at the University of Auckland, New Zealand, she came across the field of continuum mechanics.
