Dennis Valbjørn Christensen

Short CV

Dennis Christensen completed his bachelor’s and master’s degrees at the University of Copenhagen, which was followed by PhD studies at the Technical University of Denmark. Afterwards, he continued with tenure track and tenured positions at the Technical University of Denmark and as a Hans Fischer Fellow of the Institute for Advanced Study at the Technical University of Munich. He has completed eight external stays (2½ years) at various universities, including Harvard University, U. C. Berkeley, Technical University of Munich, University of Basel, Bar-Ilan University, University of Copenhagen, CNR Spin Italy, and Paul Scherrer Institute. Dennis‘ research pivots around modifying and visualizing the functional properties of oxide energy materials particularly using magnetic microscopy.
