Research

Our research focuses on the development of X-ray techniques to explore nature in 3D and 4D (3D+time), from the microscale down to the nanoscale, and from seconds down to femtoseconds. The unique penetration power of X-rays allows the study of the inner structure of matter in a non-destructive manner. Furthermore, their short wavelength allows the study from the macroscopic down to the atomic scale. These properties, together with the advent of high-brilliance sources, such as diffraction-limited storage rings (MAX IV) and X-ray free-electron lasers (European XFEL), offers the possibility to develop novel X-ray microscopes to explore nature in ways not possible before.

We are frequent users of the MAX IV synchrotron facility and the European XFEL.

Our research topics include:

  • Simulation of X-ray instruments at high-brilliance sources
  • Conceptual design and implementation of X-ray microscopes
  • Coherent X-ray imaging
  • Phase retrieval
  • Fast reconstruction algorithms based on machine learning and other state-of-the-art approaches.

Some ongoing research projects are described below:
