Senior Researcher, Associate Professor


Technical University of Denmark

Research Interests

Research topics: Medical Magnetic Resonance Imaging (MRI) techniques and applications. Sequence development, spectroscopy, functional og dynamic measurements, visualization and MR physics.

Overview: The research focus is MRI methodology and technology in a broad sense. This includes imaging and spectroscopy methodology, mostly of general nature or for brain. The developed techniques were used in studies of multiple sclerosis, depression, MLD, and muscle energetics, for example. Recent research includes hyperpolarized imaging, fast spectroscopic imaging, motion correction, and encoding of non-MR signals in MRI, e.g. for artifact correction. Interests also include MR fundamentals, and development of widely used educational material and software made freely available via the DRCMR homepage.

Affiliations: Senior Scientist and group leader at the DRCMR (http://www.drcmr.dk/acquisition). Also Associate Professor at the DTU Center for Magnetic Resonance (http://www.cmr.healthtech.dtu.dk/) and active in the Center for Hyperpolarization in Magnetic Resonance (http://www.hypermag.dtu.dk/).

Teaching: Course in MRI understanding at DRCMR (http://www.drcmr.dk/mri-course) for a broad audience, and various technical MRI courses at DTU (see list via links above).
