Research Interests: I am heading the Mineral, Structure and Function group of the Ludwig Boltzmann Institute of Osteology. In our group we investigate the structure of bone of healthy individuals and the change of this structure during ageing and in (rare) diseases. Special emphasis is put on the mineralization of the bone material and its mechanical behavior. Our group is an interdisciplinary team consisting of physicists and biologists that is united in the goal to combine various methods from different scientific disciplines, like physics, materials science, chemistry or biology to better understand the different aspects of bone - from the material to the endocrine organ.

Bone properties in osteogenesis imperfecta: what can we learn from a bone biopsy beyond histology?Publication in Computational Materials Science:
In the framework of the FWF funded Project The influence of the coordination of cross-links on the mechanical properties of polymers a publication was accepted in Computational Materials Science. In the article A high coordination of cross-links in fibre bundles prevents local strain concentrations we investigate how deformation is distributed in an aligned fiber bundle depending on the coordination of cross-links. We show that a higher coordination of cross-links leads to a more homogeneous strain distribution preventing local strain concentrations. As such strain concentrations may lead to irreversible damage in the structure, an increase in cross-link coordination is beneficial for the mechanical performance for the bundle. These findings are completed by a detailed analysis of the resilience of the structures for two types of cross-links and different cross-linker densities.
