• Research interests

Cosmology and Large Scale Structure of the Universe Numerical Simulations of large-scale structure, IGM and Galaxy Clusters. Physics of Intra-Cluster Medium in Galaxy Clusters and Galaxies-ICM interplay Physics of Intergalactic Medium and Galaxies-IGM interplay Chemical Enrichment of Intergalactic Medium and Intracluster Medium The focus of the research activity is mainly on the chemo/thermodynamical properties of baryons in both gaseous and stellar component, and on their evolution across the Universe history in different environments (voids, diffuse medium, collapsed objects). Particularly, the interest is on the interplay between gas and galaxies in both Galaxy Clusters and IGM, on the galactic feedback mechanisms at different ages, and on the evolution of galactic properties and IGM properties at both low and high redshifts. A specific attention is given to the chemical enrichment of the universe.

• Working experience

He has accumulated a significant experience in collaborative working within large international groups being involved in large programs of numerical simulations and european networks. In particular, he is actively developing the Gadget code widely used for cosmological and astrophysical simulations in collaboration with MPA group (Volker Springel, the developers' In the framework of that involvement, he has been visiting MPA institute in Garching several times between 2003 and 2009, for a total period of about a year. He has been involved in the large OWLS collaboration in Leiden, where he has been visiting in 2005 and 2007. Along with collaborators Stefano Borgani and Matteo Viel has been involved in two Virgo consortium meetings (2007 at Leiden University, 2008 at Nottingham University) for setting up collaborations and projects. He has been involved in the CosmoComp European network.

• Reviewing Activity
