Bernardi Research Group

Welcome

Bernardi

We develop and apply ab initio quantum mechanical calculations to study the dynamics of electrons and excited states in materials. Our research combines theory and cutting-edge computational tools based on density functional theory and related excited-state methods, which employ massively parallel computational algorithms and use the structure of the material as the only input. Using these methods, we can investigate electrons in materials with Angstrom space and femtosecond time resolutions, with applications in energy conversion, novel electronics and optoelectronics, and ultrafast spectroscopy.
