Luca Belluzzi carried out his Master (2004) and PhD (2009) theses at the University of Florence (Italy), being Prof. E. Landi Degl'Innocenti his advisor. The research topic was the theoretical interpretation of the linearly-polarized solar-limb spectrum, and its exploitation for the investigation of the magnetism of the solar atmosphere. In 2010 he started a post-doctoral stay at the IAC, in the group of Prof. J. Trujillo Bueno, with whom he had previously collaborated. At the IAC, Luca Belluzzi could expand his expertise by developing numerical methods for solving the non-LTE radiative transfer (RT) problem in the presence of polarization phenomena, and he started working on the RT modeling of scattering polarization and the Hanle and Zeeman effects in strong chromospheric lines, taking partial frequency redistribution (PRD) effects into account. Luca Belluzzi is presently a scientific staff member of the Istituto Ricerche Solari Locarno (Switzerland). He is team member of both the Chromospheric Ly-Alpha SpectroPolarimeter (CLASP-1) and the Chromospheric Layer SpectroPolarimeter (CLASP-2) sounding rocket experiments. As member of the POLMAG research group, he is contributing to the development of WP-3 and WP-4.
