Full professor in General and Inorganic Chemistry (1/2005 on), author/coauthor of 175 refereed papers, 3 book chapters and a patent. H-index: 33 (Google Scholar), 31 (Scopus), >3700 citns (Scholar).
His interests are mainly focused on the interaction of molecular systems with semiconductor surfaces with the creation of complex surface species via wet chemistry, mainly followed by the application of conventional and synchrotron-excited photoemission and related techniques. Visiting scientist at the University of Wisconsin-Madison in 1987, '88 (Fulbright fellow) and '89. Local responsible in both a Science (1992-95) and a Human Capital & Mobility (1994-'96) European research project on metal clusters; national (2005-07 and 2003-05) and local (2019-22, 2000-02, 1997-99) responsible in previous MIUR National Projects. A member of the ELETTRA review committee on Surface and Interfaces (2004-10); Delegate elected of the National Chemistry Society for the Inorganic division (2007-12); Expert for evaluation of project applications and monitoring of the Sixth and Seventh Framework Programme of EU; A referee for several scientific journals and a project referee for various foreign and Italian universities, ASI-Agenzia Spaziale Italiana, MIUR and other National Research Institutes. His research topics can be summarized as: Photoemission studies of molecule-surface interaction, coordination compounds, molecular clusters and nanoparticles, supported catalysts; Synchrotron radiation-excited photoemission studies on: High-Tc superconductors, organic and organometallic overlayers adsorbed on semiconductors, heterojunctions, metal overlayers on semiconductors; EXAFS studies of supported clusters and nanoparticles; XPD studies on ultrathin layers of transition metal oxides on metal surfaces. Awarded in 2014-15 and 2015-16 for excellence in university teaching by the Faculty of Sciences of La Sapienza.
