Curriculum Vitae

MORITZ SCHAAR was born in Halle/Saale, Germany in 1988. He received his Master of Science in Medical Engineering Science in 2013 from the University of Lübeck, Germany. During his study he was mainly interested in medical imaging and medical image processing. In 2013 he wrote his master thesis at the Philips Technologie GmbH – Innovative Technologies, Research Laboratories in Hamburg about rib segmentation in thorax radiographies. Since 04/2014 he is a student of the Graduate School for Computing in Medicine and Life Sciences and works in the field of combined reconstruction of Computed Tomography and Nuclear Medical Imaging in cooperation with the MiE medical imaging electronics GmbH in Seth, Germany.

The project is financially supported by the TANDEM II project (grant no. 122 13 002).
