Stefan Sieberer's post-doctoral dissertation titled "Advances in Static and Fatigue Behaviour of Fibre-reinforced Composite Materials and Structures" was written at the JKU's Institute of Structural Lightweight Design  and focuses on characterizing both the strength and fatigue behavior of fibre-plastic composite materials and structures made from these materials. The applied research is based on experimental methods backed by numerical and analytical methods.

Those pursuing a habilitation/post-doc undergo an academic evaluation in regard to special qualifications that proves their ability to independently conduct academic/scientific research and teach the entire depth and breadth of their selected subject area [facultas docendi], This, in turn, is the prerequisite to grant authorization to teach that particular subject area.
