Felix Lehmkühler received his phd in physics at TU Dortmund (Germany) for his work on formation processes of gas hydrates. Afterwards he was a postdoc at the photon science division at DESY (Hamburg, Germany) focusing on coherent X-ray scattering experiments at synchrotron and free-electron laser sources. Since 2014, he is a senior scientist leading the activities of the complex liquids team at DESY. His research focusses on structure and dynamics in colloidal systems, aqueous solution and water using modern X-ray light sources.
