My main research interest is on the development of computational models in the fields of chemistry, biophysics and materials.
Plasmonics. One of my main research activities has been to extend the capabilities of continuum models, going beyond the study of solvation effects in quantum-chemistry. Over the years I have developed and improved an original approach to treat the effect of plasmonic devices (metal nano-particles, graphene nano-disks, etc.) on molecular excitations and energy transfers, allowing for the first time to give a detailed chemical perspective on plasmon-enhanced phenomena. Recent applications focus on light-harvesting complexes and to the characterization of excitonic properties in the presence of plasmonic nano particles. (watch this presentation or this video on the topic).
Condensed matter. In pursuing new ways to apply continuum and multiscale models to different research fields, I have developed a novel model of solvation, coupled to a plane-wave pseudo-potentials-based first-principles simulation package. By exploiting my experience on quantum-chemistry approaches, I have been able to produce a model with a sound and well-defined physical base, allowing for the first time to acquire the level of accuracy of chemical approaches, but with a much broader spectrum of applications. Since the original formulations, I have been continuously involved in adding new features to the model, among which the calculation of excitation energies, the description of charged systems, and the development of periodic boundary conditions corrections schemes. The capabilities of the model have attracted several collaborations over the past years, with a large range of applications that have been and are currently pursued in the fields of surface science and biophysics.
Machine learning. Eventually, in developing new approaches and algorithms, I have always been particularly keen on exploiting novel numerical methodologies, with a particular interest on machine-learning algorithms. During my PhD I have been involved in the improvement and characterization of a first-principles-based neural-network interaction potential for silicon. The acquired experience has motivated my recent on-going work on a neural-network approach to compute the spectral-densities and excitonic properties of complexes of pigments in natural light-harvesting systems.
