University Researcher (PhD)

My research field is experimental material physico-chemistry, with an emphasis on the characterization of nuclear materials such as nuclear fuels.

My expertise lies on X-ray spectroscopies (XANES, EXAFS, HERFD-XAS, XES) at both synchrotron radiation facilities and at laboratory scale, as well as ion beam analysis (RBS, NRA, PIXE, PIGE) and irradiation/implantation of materials.

I have recently developed positron annihilation lifetime spectrometers dedicated to the study of radioactive materials. One is available in the Accelerator laboratry and another one is in used at the European JRC Karlsruhe (Germany) hot laboratory.

As manager of the Center for X-ray Spectroscopy, I am currently working on the development of several new laboratory scale XAS/XES spectrometers aiming to enhanced the material characterization capabilities at the Kumpula campus, especially in the field of nuclear materials.
