Volkmar Schulz obtained his Dipl.-Ing. degree in the field of Information Technology and his Dr.-Ing. degree in the area of electrodynamics and integrated optics from the University of Paderborn. He started his industry career in 2000 at Philips Research Laboratories in Hamburg, Germany, in MR hardware, and in 2005 moved to the PET physics group at Philips Research in Aachen, Germany, where he focused on integrated PET-MRI systems. Since 2009 he is a group leader and senior lecturer at the institute of “Experimental Molecular Imaging Systems” at the RWTH Aachen University focussing on physics and instrumentation of molecular imaging systems. In 2011, Volkmar was appointed Principal Scientist at Philips Research. Since the beginning of 2013, he has been a full professor and heads the department of "Physics in Molecular Imaging Systems" (PMI) at RWTH.

His department aims exploring the physical limits of medical imaging technologies with a strong focus on instrumentation and machine learning. This includes the combination of existing modalities like Magnetic Resonance Imaging (MRI, Positron Emission Tomography (PET) and other novel imaging modalities like Magnetic Particle Imaging (MPI). The research areas are ranging from novel sensor concepts, new detector geometries, crystal identification algorithms, new image reconstruction and dedicated MRI sequences for MR-based attenuation correction techniques and machine learning methods for automatic Computer Decision Support (CDS) systems. In 2015, the department built the world’s first fully digital preclinical PET-MRI systems for imaging of mice using the digital SiPM from Philips Digital Photon Counting.
