Overview
I am a Reader at Cardiff School of Engineering. My current research interest lies mainly in the field of hydrodynamic turbulence. One main stream of activity is devoted to the LES modeling of Newtonian turbulence, while a second one deals with turbulence in dilute polymer solutions. From the point of view of the simulation the technique is high fidelity computational methods using pseudo-spectral approaches both for Direct Numerical Simulations and LES simulations.
Prior to my first appointment as Senior Lecturer in 2015, I was Associate Professor at the University of Bologna Italy. I have published over 50 journal papers.
I am Principal Investigator (PI) in the EPSRC Grants EP/R042640/1 on Multiscale dynamics in the turbulent/non-turbulent interface of jets and plumes
Biography
I received my Master Degree in Mechanical Engineering (cum Laude) in 1997 at University of Rome La Sapienza where in 2001 I also received my PhD Degree in Meccanica Teorica e Applicata with a thesis "The influence of polymer additives on the structure of wall turbulence".
Since 2001 I started a collaboration with the Fluid Dynamics group at the Department of Mechanical and Aeronautical Engineering of La Sapienza with a Research Fellowship. Moreover I was a Research Assistant at the ETH Zuerich between 2001 and 2003.
My scientific activity deals with numerical simulation and data analysis in fluid mechanics, namely turbulence in rheologically complex fluids and statistical analysis of wall turbulence. I had collaborations with ETH Zuerich, the Weizmann Institute of Science and Chinese University of Hong-Kong.
Since 2004 I taught Computational Fluid Dynamics at the Second School of Engineering of University of Bologna and since 2006 Numerical Fluid Dynamics at the Biomedical Campus in Rome. I was also involved in the CICLoPE (Centre for International Cooperation in Long Pipe Experiments) project as responsible for the Computational group.
At the end of 2011 I became Associate Professor in Fluid Dynamics and in February 2014 I obtained the National Scientific Qualification as Full Professor in Fluid Dynamics in Italy. In 2015 I have been appointed Senior Lecturer at Cardiff University where I have taught in the Mechanical Engineering Degree.

My research activity is mainly in the field of turbulence. One main stream of activity is devoted to the LES modeling of Newtonian turbulence, while a second one deals with transition and turbulence in dilute polymer solutions.
From thepoint of view of the simulation the technique is high fidelity computational methods using pseudo-spectral approaches both for Direct Numerical Simulations and LES simulations. The tools used for the investigation might vary. The favorite one is the scale by scale budget of turbulent kinetic energy for non homogeneous flows which has been extended both to LES modeling and to viscoelastic flows.
