Introduction
I attended the School of Material Engineering at the University of Lecce (Italy), and graduated in 1999 with first class honors received thePh.D. degree in 2003. From September 2005 to December I held a visiting position at the Center for Automotive Research of prof. Rizzoni at the Ohio State University, Columbus, OH. In November 2001 I joined the Faculty of the University of Lecce as Assistant Professor and in December 2014 as Associate Professor.
