Research interests

His research activity has focused on the theory of low-dimensional systems, in particular the structural, electronic and optical properties of metal and semiconductor surface and interfaces. In recent years the central topic of his research has been the investigation of the structural, electronic and optical properties of nanostructures. This work has been done in close collaboration with leading experimental and theoretical groups in the field within a large number of national and international research projects. He is actually leading the research group on low-dimensional systems and nanostructures (>10 members, www.nanomodelling.unimore.it) . He has supervised more than 10 PhD thesis and more than 20 master thesis. He has obtained a large numbers (>30, several as co-ordinator)national and international research grants (PRIN 1997, 1999, 2002, 2005, 2007; CNR, INFM-PRA, Bilateral Projects MAE; Vigoni Projects, Galileo Projects, Università Italo-Francese, HPC, UE VI e VII framework). He has participated to the organization of a large numbers (>30) conferences (several as chairman) and he has presented a large numbers of invited talks (>50) at national and international conferences and in national and international research groups.. He has published more than 200 articles, several review articles and chapter of books. He is co-editor of two books on low-dimensional silicon structures and is author (with L. Pavesi e F. Priolo) of the book "Light Emitting Silicon for Microphotonics", Springer Verlag, Berlin 2003 and (with V. N. Borisenko) of the book "What is What in the Nanoworld",Wiley-VCH, Weinheim, first edition 2004, second edition 2008, third edition 2012. Since long time is also active regarding the link between science and society. He published 2012 "L'universo è fatto di storie non solo di atomi" (Neri Pozza) on scientific misconduct and 2013 "Non ho nulla da rimproverarmi. 1911 Stoccolma e dintorni" (Scienzaexpress), a theater piece, several times on stage,in particular 2011 at teh Festival della Scienza", Genova.
