Katharina Jähn-Rickert, PhD is a principal investigator at the Department of Osteology and Biomechanics at the University Medical Center Hamburg-Eppendorf, D.

Her work focuses on the functional investigation of osteocytes in bone physiology and pathologies utilizing state-of-the-art imaging approaches – thereby she aims to work on the interface of different disciplines i.e. biomechanics, molecular, clinical, and translational research.

Initially, she studied Biochemistry in Leipzig, D and went on to do her Ph.D. with Cardiff University, UK and the AO Research Institute Davos, CH.

Within a European Space Agency funded project, she investigated the impact of ex vivo bone organ culture on osteocyte viability, and the potential of high frequency low amplitude loading to prevent microgravity-induced bone loss.

During her post-doctoral work at the University of Missouri-Kansas City, USA, she demonstrated that soluble factors from skeletal muscles are beneficial to osteocyte viability, and further showed that osteocytes can acidify their microenvironment during lactation-induced osteocytic osteolysis in mice.

In Hamburg she also contributed to the description of a novel regulator of bone remodeling, while also demonstrating that a new magnesium-silver-alloy implant enabled physiological fracture healing in a collaborative effort with the Helmholtz Center, D.
