Alexander Haumer studied Medicine at the Paracelsus Medical University of Salzburg (Austria) and the Mayo Clinic Rochester (USA). Currently he is enrolled in the MD/PhD program in tissue engineering and regenerative medicine at the University of Basel. There he studies bone regeneration by use of bone marrow and adipose tissue derived mesenchymal stromal/stem cells (MSCs). These cells are used to generate osteogenic grafts, which they propose as bone substitutes. Alexander Haumer’s specific interest lies in the immunological processes influencing the bone regeneration, such as macrophage invasion. Moreover, the detection and quan¬tification of bone formation, vessel ingrowth and immune cells in engineered osteogenic grafts in vivo remains a critical issue in bone tissue engineering. To address these unmet needs, he investigates the use of state-of-the-art imaging techniques including: tomography, magnetic resonance with or without contrast agents, and intra-vital staining coupled to two-photon microscopy. His overall supervisor at the biomedical MR research group is Arend Heerschap .
