Stefano Deabate received his diploma Thesis in Chemistry from the University of Turin, Italy, in 1997. In 2001, he obtained his Ph.D. in Physical Chemistry from the University of Montpellier II, Montpellier, France. He was, subsequently, a postdoctoral fellow in the same University, until he became Assistant Professor in 2003 at the Chemistry Engineering School of Montpellier, where he has been teaching on material science, analytical chemistry and physico-chemistry (electrochemistry and vibrational spectroscopy).

His research interests are centered around the investigation of the mass/charge transport mechanisms in condensed matter. His work comprises materials for both electrochemical energy storage (Ni electrode) and production (polymer electrolytes for low temperature fuel cells). The focus of his research is both a better understanding of fundamental issues and the development of novel characterization methods coupling in situ vibrational spectroscopy (IR and Raman) to electrochemical devices.
