Short presentation
My research focuses on the refinement of methods related to Resonant Inelastic X-ray Scattering (RIXS), especially the application to molecular systems. I am spokesperson for VERITAS at the MAX IV laboratory, a beamline dedicated to this purpose. I investigate non-linear X-ray physics, e.g., Stimulated X-ray Raman Scattering (SXRS) at X-ray free-electron lasers, primarily via an imaging spectrometer which we has been developed in Upppsala, and installed at the European XFEL in Hamburg.
