His Phd work focused on studies that deal with the kinetics and mechanisms of elementary reactions of gases, on bimetallic surfaces. After working as a visiting scientist at Synchrotron Radiation Facilities, Fermi Elettra, Italy, as a post-doctoral researcher at FORTH/ICE-HT, Greece and as a post-doctoral employee at the University of California, Riverside, he joined the Fiend lab in January 2015. His current research focuses on the study of structural and catalytic properties of oxygen-activated gold surfaces under UHV conditions, with the use of high resolution electron energy loss spectroscopy (HREELS) and temperature-programmed reaction spectroscopy (TPRS). - ## People [Former Group Members 2010 to present](/people/former-group-members-2010-to) [Postdoctoral Researchers](/people/postdoctoral-researcher)
