More Detailed description: After an initial research period in experimental condensed matter physics, focused on the optical properties of defects and color centers in insulating matrices, I have been working for many years in the field of first-principles calculations of the structural, electronic, and optical properties of materials.

During my PhD thesis, I began focusing on ab-initio calculations within density functional theory (DFT) and many-body perturbation theory (MBPT), studying the electronic properties of wide band-gap semiconductor compounds, such as GaN, including electronic self-energy corrections. Since 1996, I have worked on the electronic and linear and nonlinear optical properties of various semiconductor and metallic surfaces, both bare and covered by atomic or molecular adsorbates. In particular, I became an expert in calculating reflectance anisotropy spectra (RAS) and surface differential reflectivity (SDR) spectra.

After 2005, my research focused on first-principles studies of many-body effects in the surfaces of semiconductor materials with both wide and narrow band gaps, as well as on the dielectric response and electronic excitations of low-dimensional systems such as Ge and Si nanowires. In recent years, my main research interests have shifted to two-dimensional materials, organic compounds, and materials for energy applications such as perovskites.

Through my work, I have gained expertise in computational physics and familiarity with the most modern theories and computational tools for first-principles electronic structure calculations (Car-Parrinello, GW method, BSE exciton calculations, parallel computing). I am a member of the developer/superuser team of the many-body code Yambo (www.yambo-code.org).
