Peter Krüger studied Physics, Mathematics, Chemistry and Philosophy in Berlin (FU), Innsbruck and Heidelberg and graduated with a PhD from Heidelberg working with Anton Zeilinger and Jörg Schmiedmayer. After postdoctoral research studies with Claude Cohen Tannoudji and Jean Dalibard as Humboldt and Marie Curie fellow at the ENS Paris, in 2007 he was appointed to Full Professor at the University of Nottingham to establish the Midlands Ultracold Atom Research Centre as a co-founder. In 2016 he moved his research group to Sussex, where he is Research Professor of Experimental Physics. He heads the Quantum Systems and Devices group and is founding director of the Sussex Programme for Quantum Research.

Krüger's field of specialisation is atomic physics and ultracold quantum gases. He pioneered integrated circuits for cold atoms, so-called atom chips, invented magnetic microscopy based on Bose-Einstein condensates. His research interests continue to span across fundamental questions of quantum physics to technology applications. He is part of the UK National Quantum Technologies Programme's leadership team. Current projects include quantum magnetometry applications in brain imaging (magnetoencephalography), electric vehicle batteries and microscopic imaging of novel micro- and nanostructured materials and electronic devices.
