Andrea Vezzosi is a postdoctoral researcher in the group of Prof. Ursula Rothlisberger at the Institute of Chemical Sciences and Engineering, EPFL (Switzerland). He earned his Ph.D. in Physics and Nanosciences from the University of Modena and Reggio Emilia in 2024, where he investigated spin–orbit coupling and topological states in core–shell semiconductor nanowires. During his doctoral studies, he developed nwkp, an open-source Python library for computing the band structure of core–shell nanowires using a multiband k·p perturbation theory approach. In 2024, he joined Prof. Rothlisberger’s group, where his research focuses on multiscale numerical design and characterization of perovskite solar cells, combining ab initio and classical molecular dynamics simulations. His work is carried out in close collaboration with the experimental group of Prof. Michael Graetzel, aiming to bridge atomistic insights with device-scale performance. He has authored more than ten publications in leading peer-reviewed journals, including Physical Review B, Advanced Materials, Nano Letters, and Angewandte Chemie.
