Research Interests: The research themes I developed in these years investigate soft systems comprising many interacting particles, biological flows, self-organization and collective phenomena, like synchronization, and cell motility. Physical phenomena such as dissipation and irreversibility in non-equilibrium systems on the one hand; and the mathematical structures needed for their description, on the other hand, are a source of inspiration – the main driving force which fascinates me and sustains my interest in research. My aim is to understand how coherent collective behaviors, that take place for instance at microscopic scale in living systems or in collections of synthetic active particles, can emerge from physical interactions. My approach to study these problems combines analytical techniques from dynamical systems theory and fluid dynamics as well as numerical methods.

Research interests: I am interested in statistical and computational physics in general, with applications to soft matter and glassy physics. Within the Soft Matter Group I am working on flocking models with disorder (with M. Cristina Marchetti) and on the crumpling of thin sheets (with Mark Bowick), while maintaining previous collaborations on spin-glass physics.

Achievements: a) Development of the Tethered Monte Carlo formalism b) Detailed equilibrium and off-equilibrium study of the low-temperature phase of the Edwards-Anderson spin glass, in particular describing its non-coarsening dynamics and establishing a statics-dynamics relationship c) Establishing the presence of a thermodynamic glass transition for a spin glass in a field below the upper critical dimension.

Recent Publications: (1) Minimal model of active colloids highlights the role of mechanical interactions in controlling the emergent behavior of active matter (2) Probing the spin-glass phase with non-equilibrium measurements: statics-dynamics equivalence through the fluctuation-dissipation ratio  (3) Temperature chaos is a non-local effect
