Research interests

Daniele Varsano activity is focused on the understanding and predicting the electronic and optical properties of nanostructured materials and biological molecules performing first principle simulations at the DFT level and beyond (by using many-body perturbation theory (MBPT) methods).My interests are dedicated to the methodological development of computational schemes based on quantum-mechanical descriptions of interacting electrons and light-matter interaction for theoretical spectroscopies, with applications in the field of biophysics, nanotechnology and energy conversion. A list of topics includes:

* First principle calculation for electronic and optical properties of low-dimensional systems.
* Methodological development in TDDFT and Many Body Perturbation Theory.
* Multiscale Modelling with Electron Correlation.
* Optical properties of light-harvesting molecules for photovoltaic applications, and biological photoreceptors.
* Development of the TDDFT and MBPT code Yambo (http:www.yambo-code.org)
