Researcher biography
After obtaining a Master degree in Biomedical Engineering at the Ilmenau University of Technology, I completed a PhD on multimodal imaging at the University Children's Hospital and ETH Zurich, Switzerland. In 2014 I joined the Centre for Advanced Imaging at the University of Queensland as a National Imaging Facility Fellow, where I pioneered the application of deep learning methods for quantitative imaging techniques, in particular Quantitative Susceptibility Mapping, in the group of Prof Markus Barth.
In 2019 I joined the Siemens Healthineers collaborations team at the MGH Martinos Center in Boston during a 1 year industry exchange where I worked on the translation of fast imaging techniques into clinical applications.
