My research interests concern the physics of disordered states of matter, with particular focus on the microscopic mechanisms of glass formation and on glass structure. I am also interested in modeling the peculiar phase behavior, structure and dynamics of soft condensed matter.
My work is based on the methods of statistical physics and on computer simulations. Over the years I developed a computational approach based on reproducible research, high-performance computing and on high-level simulation frameworks like atooms, which I develop.

I developed a python framework called atooms to perform computer simulations and analyze their results. It provides an expressive, high-level interface to the main objects of particle simulations.
Atooms is a collection of python packages that provide a high-level, yet efficient framework to deal with particle-based simulations, such as molecular dynamics or Monte Carlo. It is composed by a base library and additional packages that implement complex simulation strategies or analysis tools.

Atooms-pt is the first simulation package I built on top of the atooms framework. It implements a multi-GPU parallel tempering simulation and relies on RUMD, an efficient molecular dynamics code developed by Glass and Time at the University of Roskilde.
The atooms-pp package provides python tools to compute static and dynamic correlation functions from particle-based simulation data.
Francesco Turci contributed a jupyter notebook showing how to compute static and dynamic correlations of a Lennard-Jones mixture using the postprocessing package.Tutorial » Notebook »
Transition path sampling
The atooms-tps package, developed in collaboration with Francesco Turci, provides a generic frontend to transition path sampling simulations, which allow to sample rare fluctuations in the trajectory space of a dynamical system.
