Biography

Henrik Ronnow was born in Copenhagen in 1974. He was awarded his master's degree in physics in 1996. Having earned his doctorate in 2000, he left Denmark for training at the Laue-Langevin Institute in Grenoble. Between 2000 and 2002, he held a Marie Curie Fellowship hosted by the Atomic Energy Commission. In 2002 he was appointed as an invited researcher at the NEC Laboratories in Princeton, then at the University of Chicago's James Franck Institute. In 2003, he became a researcher at the Laboratory for Neutron Scattering (Swiss Federal Institute of Technology in Zurich) and at the Paul Scherrer Institute. In 2007 he was appointed Assistant Professor at Ecole Polytechnique federale de Lausanne (EPFL). In 2012 he was promoted to Associate Professor.
