Research activity Spinglasses and Inverse Transition I have studied the phase diagram of the Blume-Capel model with quenched disorder. The phase diagram is characterized by spin-glass/paramagnet phase transitions of both first and second order in thermodynamic sense. Numerical simulations are performed using the Exchange- Monte Carlo algorithm, providing clear evidence of inverse freezing. The main features at criticality and in the phase coexistence region are investigated. The whole inverse freezing transition appears to be first order. Structural Glasses Through the dynamics equations of a s + p multi-spin interaction model, I have studied the interrelation of dynamic processes active on separated time-scales in glasses. I analyzed the dynamic properties of a model for slowly relaxing glassy behavior with up to three timescales. This is a generalization of the p-spin model with quenched disorder, that is known to heuristically reproduce all the basic features of structural glasses and whose dynamics above a certain temperature ("dynamic" or "mode coupling") is equivalent to the dynamics of the schematic mode coupling theory (MCT). Continuum Mechanics and Molecular Dynamics simulation I am investigating the coupling of Continuum and Atomistic Mechanics through the Andersen- Parrinello-Rahman Lagrangian: a mathematical tool, used in Molecular Dynamics in order to generate the isobaric ensamble, which allows us to describe a scenario where discretes and continuum degrees of freedom coexist.

3 Active Matter I m postdoctoral fellow in active matter in the research group of R. Di Leonardo. I am investigating Escherichia coli motility both by means of extensive molecular dynamics simulations and through analytically solvable models. My research interests are about the role played by confinement on active system (dense or dilute). I focus my attention on random external potentials, e. g., active particles in speckle patterns, confining structures, e. g., active particles in microfluidic devices, analytically solvable models in one dimension, e. g., first-passage times problems and steady states pdf for active systems. Computer Skills Operating systems: Linux, Mac OS X and Windows. Extensive programming experience in C: Montecarlo simulations and Parallel Tempering technique, numerical investigation of first- and second-order phase transtions, numerical solution of the Mode Copling equations, Molecular Dynamics simulation in microcanonical, canonical and isobaric ensamble. Basics of parallel programming (MPI and OpenMP) and GPU programming (CUDA). Scripting languages: awk, python. Computational software: Mathematica.
