Jochen Küpper

Jochen Küpper FRSC is a German chemist and physicist, group leader at the Center for Free-Electron Laser Science, Deutsches Elektronen-Synchrotron DESY, and Professor of Physics and Professor by courtesy of Chemistry at the University of Hamburg, Germany.^[1]

He is best known for his pioneering work on the control of complex neutral molecules, including the spatial separation of structural isomers and their laser-alignment and mixed-field orientation. He develops novel techniques to control the external and internal degrees of freedom of neutral molecules and exploits these well-defined samples in experiments to image their nuclear and electronic structure and dynamics.^[1]

Awards[]

Jochen Küpper received several awards, including the prestigious Nernst Haber Bodenstein Prize of the German Bunsen-Society for Physical Chemistry^[2] in 2009 and an ERC Consolidator Grant in 2013. He was elected as Fellow of the Royal Society of Chemistry in 2014.^[3]

Life[]

Jochen Küpper went to Lise-Meitner-Gymnasium in Leverkusen, Germany. From 1991 to 1996 he studied Chemistry at Heinrich Heine University, Düsseldorf, Germany and at University of Pittsburgh, Pittsburgh, PA.^[3] In 2000 he received his doctorate in Physical Chemistry from Heinrich Heine University, Düsseldorf, Germany.^[3] In 2009 he received the Habilitation in Experimental Physics for his work on the control of large, neutral molecules at Free University Berlin.^[3]

He was Feodor-Lynen Fellow of the Alexander von Humboldt Society at the University of North Carolina at Chapel Hill, NC, USA from 2001 to 2002 and at the FOM-Institute for Plasma Physics "Rijnhuizen" in Nieuwegein, The Netherlands.^[3] He then became project leader in the Department of Molecular Physics at the Fritz Haber Institute of the Max Planck Society in Berlin-Dahlem, Germany.^[3]

Since 2010 he is a Professor of Physics at University of Hamburg and a research group leader at the Center for Free-Electron Laser Science and DESY, Hamburg, Germany and since 2015 he is a Professor by courtesy of Chemistry at the University of Hamburg, Germany.^[3]
