Research Interests

My research is focused on understanding, modeling and predicting the structure-property relationships in organic functional materials and hybrid interfaces.

Such materials are considered as potential candidates for electronic (e.g. OLED, OFET), photovoltaic (e.g. OPV), thermoelectric and energy-harvesting applications.

The research lines are focussed on:

1. Electron and energy transfer theories.
2. Excited state non-adiabatic dynamics.
3. Doping processes and polaron transport mechanisms.
4. Ultrafast electronic and vibrational spectroscopy.

The research activity encompasses the extensive use of state-of-the-art theoretical methods and computational modelling techniques.
