Research Management

Christian Klemt, MSc PhD - Research Program Manager

Christian Klemt completed his undergraduate degree in Mechanical Engineering at Berlin Institute of Technology. He joined Queen Mary, University of London to pursue a masters degree in Biomedical Engineering with a focus on musculoskeletal mechanics. To broaden his interest in musculoskeletal biomechanics, Christian joined Imperial College London in 2015 for a PhD aiming to customize musculoskeletal shoulder modelling utilizing Magnetic Resonance Imaging in order to more precisely assess joint functionality and joint stability for both native joints as well as joint replacements. Following the completion of his PhD, he joined the Bioengineering Laboratory at Massachusetts General Hospital/Harvard Medical School to study in-vivo hip and knee biomechanics of patients with total joint replacement. Additionally, Christian’s Post-Doctoral research involved the retrospective analysis of patient data to identify risk factors for poor patient outcomes and implant failure. Recently, Christian developed and validated artificial intelligence technology to predict post-operative outcomes and complications for patients following hip and knee arthroplasty surgery in order to assist clinical decision-making.
