Kirsten Schnorr received her PhD in physics in 2014 from Ruprecht Karl University Heidelberg on XUV Pump-Probe Experiments on Electron Rearrangement and Interatomic Coulombic Decay in Diatomic Molecules under PD Dr .Robert Moshammer at the Max Planck Institute for Nuclear Physics. In 2015 she was awarded a Peter Paul Ewald Fellowship from the Volkswagen Foundation for studying non-linear relaxation processes in real time, which she carried out in the Physical Chemistry Department at University of California Berkeley in the group of Prof. Dr. Stephen Leone.

Since 2018, Kirsten has joined the SwissFEL team to work on a new endstation for atomic, molecular and non-linear physics, the Maloja instrument. She was responsible for designing, building and bringing the endstation into operation.

Kirsten is interested in atomic, molecular and nonlinear science with XUV and X-ray radiation. Specifically, she studies photo-induced ultrafast relaxation mechanisms in atoms, molecules and nanoparticles by performing time-resolved experiments at Free-Electron Lasers and High Harmonic Generation sources. One of her main research interests is to understand and steer non-local relaxation processes, like Interatomic Coulombic Decay and Electron Mediated Decay, by exploiting the multi color pump-probe schemes with ultrashort X-ray pulses.
