Curriculum Vitae
MANDY AHLBORG (maiden name Grüttner) was born in Berlin, Germany in 1985. She received her M.Sc. in Computer Science from Technische Universität München in 2011. In 2010 she wrote her Master's Thesis "Tumor Monitoring - Implementation of Growth Criteria and Segmentation" at Brainlab in Feldkirchen. Since 2011 she works as a researcher at the Institute of Medical Engineering in the field of Magnetic Particle Imaging (MPI). She administered and worked in several MPI research projects. Together with the team of the Institute of Medical Engineering she won the German High Tech Champions Award 2014 for the category Medical Engineering and the first place of the German High Tech Champions Award Science Slam 2016 – an award created by the Fraunhofer-Gesellschaft. In 2015 she received her PhD and won the Fokusfinderpreis for her thesis. She joined the Fraunhofer Research Institution for Individualized and Cell-Based Medical Engineering IMTE in 2020 as leader of the group Instrumentation.
