Présentation
Education:
==========
**2019:** Habilitation Degree in Physics, Université Rennes (France)
**2004:** Ph.D in Physics, Université Paul Sabatier at Toulouse (France); Advisor: Prof. David Mainprice
About:
======
Dr Pedesseau is an Associate Professor at the INSA Rennes (FOTON Institute - CNRS) whose work is aimed at the understanding of physical processes in the III-V semiconductor nanostructures for silicon photonics, the hybrid perovskites and novel materials for photovoltaics, and optoelectronic device simulations for optical-communications. His recent scientific interests include: 1) polar surface and interface energies of semiconductors; 2) first principles simulation (including the spin-orbit effect) of mechanical stability, electronic, and optical properties of 3D and 2D semiconductors; 3) electronic structure theory beyond the DFT such as hybrid functionals (HSE), many-body corrections GW, and DFT-1/2; 4) HPC technology for exotic and highly demanding simulations in terms of the large memory footprint and extensive CPUs communications (thousands).
