Salvatore Stagira graduated cum laude in June 1994 in Electronic Engineering at Politecnico di Milano.
In June 1998 he received the PhD in Electronic and Communication Engineering at Politecnico di Milano
From 1998 to 1999 he was post-doc grantee at the National Institute for the Physics of Matter (INFM).
From 1999 to 2001 he was research scientists at the Center for Quantum Electronics and Electronic Instrumentation of the National Research Council (CNR).
From 2001 to 2005 he was assistant professor at the Physics Department of Politecnico di Milano.
In 2005 he joined the School of Industrial and Information Engineering of Politecnico di Milano, were he was associate professor in Experimental Physics. Since 2019 he is full professor in Experimental Physics.
His research activity concerns the radiation-matter interaction at high intensity in the few-optical-cycle regime, the optical compression of high energy laser pulses, the generation of coherent (by high order harmonic generation) and incoherent (by laser-plasma sources) XUV and X-ray radiation; the ultrafast spectroscopy of organic and inorganic materials.
