Dennis Meier studied physics at the University of Cologne (2000–2006) before conducting research at the University of Bonn, where he earned his doctorate in 2010 at the Helmholtz Institute for Radiation and Nuclear Physics. From 2010 to 2013, he worked as a Feodor Lynen Fellow of the Alexander von Humboldt Foundation at the University of California, Berkeley (USA). He then led a junior research group at ETH Zurich (Switzerland) from 2013 to 2016, where he also completed his habilitation. Prior to his appointment in Duisburg-Essen, Meier was a professor at the Norwegian University of Science and Technology in Trondheim. He has received numerous honors for his research, including a Consolidator Grant from the European Research Council (ERC) in 2019, the Gustav Hertz Prize from the German Physical Society in 2017, and several prestigious awards from the Norwegian scientific community. An internationally recognized expert, Meier is a leading figure in the research on functional domain walls and spin textures, exploring how the tiny structures inside functional materials can be purposefully used for next-generation technologies.
