Scientific interest

On-going research: theoretical approaches - from modelling to state-of-the-art electronic structure calculations (DFT, TD-DFT)– for linear and non linear optical responses, such as two-photon absorption, of organic chromophores and for hybrid organic/perovskites semiconductors
Past interests: topology of electron densities (InteGriTy software); projector augmented wave method (PAW); molecular charge transfer crystals; neutral-to-ionic phase transitions; density matrix approaches for modelling non linear optical properties (PhD)
