Ralf Röhlsberger received his Ph.D. from the University of Hamburg. Following a postdoc appointment at the Advanced Photon Source, he was scientific assistant at the University of Rostock where he habilitated in 2002. In the same year he received the innovation award “Synchrotron Radiation” of BESSY (Germany). After an interim professorship at the Technical University of Munich, he has been a senior scientist at DESY in Hamburg since 2003 and was deputy leader of the Experimental Facility Division at the PETRA III synchrotron radiation source project. His research interests include the development of novel x-ray scattering methods, nuclear resonant scattering, physics of thin films, magnetic properties of low-dimensional systems, and x-ray quantum optics.
