BiographyBernardo Barbiellini has been involved in fundamental research to understand matter and energy at the electronic, atomic and molecular scales. Also, his research included the use of fundamental knowledge to support design of materials for new technologies. Part of his research involves solving a class of nonlinear eigenvalue problems, known as the Kohn-Sham equations, within the Density Functional Theory (DFT), arising in electronic structure calculations for studying the microscopic quantum mechanical properties of molecules, solids and other nano-scale materials.
