His field of research is surface chemistry, surface electrochemistry, and corrosion science, with emphasis on the understanding of the structure and properties of metal and alloy surfaces and thin oxide layers. His research interests include the growth mechanisms and structure of oxide layers on metals and alloys in gaseous and aqueous environments, adsorption of inorganic, organic and biomolecules, the mechanisms of corrosion of metals and alloys at the nanoscale, passivity, passivity breakdown and localized corrosion, initial stages of high temperature oxidation, and the applications of advanced surface analytical methods such as X-ray Photoelectron Spectroscopy, Scanning Tunnelling Microscopy and Spectroscopy, and Time-of-Flight Secondary Ions Mass Spectrometry.
