The TOP project (Towards the Bottom of the Periodic Table) is lead by Kristina and funded by both the European Research Council (ERC) for the period 2018-2023 (⁓1.5 mln €) and a Megagrant Project from the Ministry of Research and Higher Education of Russian Federation for the period 2019-2021(⁓1.3 mln €). She has two groups:

  • TOP Group at The Rossendorf Beamline of The European Synchrotron (ESRF) in France, operated by the Institute of Resource Ecology at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) in Germany.
  • XAS group at The Chemistry Department of the Moscow State University in Russia.

The TOP group of Kristina studies fundamental physical and chemical properties of f-electron systems (actinides and lanthanides) through the revelation of the electronic structure and investigates the applications in which these systems play an important role. Our research is strongly oriented towards new developments in the field of advanced X-ray spectroscopy methods.

On our website, you can read the latest news, info about our research activities and group members, and view a list of our publications.

Dr. Lucia Amidani

Scientific background: Physics

Special interests: the use of XAS, XES and RIXS coupled with theoretical simulations to understand the electronic structure of solid state materials

Current status: Postdoctoral Research Fellow

After her MA degree in solid state physics, Lucia joined the group of X-ray and Synchrotron radiation of Bologna University for her PhD and a first post-doctoral fellowship. After this experience focused on the use of XAS and XES to semiconductor systems, she moved to Grenoble and joined the ID26 beamline at ESRF to study lanthanides based luminescent materials with high energy resolution spectroscopy. From 2018 Lucia is involved in the theoretical understanding of actinide/lanthanide nanomaterials.
