Laureato in fisica nel 1985. Dal 1986 opera a Firenze presso il Dipartimento di Fisica , prima come tecnico laureato, poi come ricercatore, e attualmente come Professore Associato (FIS/01) presso la Facoltà di SMFN dove insegna in corsi di base nel CdL in Tecnologia per la conservazione e il restauro dei beni culturali (di cui è presidente). La sua attività di ricerca si è svolta nell’ambito della fisica nucleare sperimentale, sia di base che applicata. Nella ricerca di base, ha studiato le reazioni fra ioni pesanti a energie da pochi MeV/A a ~20 MeV/A, con particolare riferimento all’analisi dei meccanismi di fusione-fissione e fusione-evaporazione. Per quel che riguarda la fisica nucleare applicata, è stato fra i promotori dello sviluppo del laboratorio dell’acceleratore di Firenze come centro per le analisi IBA nei settori dei Beni Culturali e dell’ambiente; in quest’ultimo campo è il responsabile delle attività che vi si svolgono. Il complesso di queste attività ha portato alla pubblicazione di oltre 160 lavori su riviste internazionali con referee, a svariate presentazioni seminariali presso Istituti e Laboratori in Italia e all’estero, e a numerose relazioni in congressi internazionali. È stato invitato come chairman a varie conferenze internazionali. È referee di numerose riviste internazionali. È stato responsabile nazionale di un PRIN dal titolo “Analisi con fasci ionici, spettrometria di massa con acceleratori e tecniche complementari per l'ambiente e i beni culturali” approvato per il biennio 2004-2005, responsabile nazionale di un esperimento del cosiddetto “quinto gruppo” INFN e Presidente del Corso di Laurea Tecnologie per la Conservazione e il Restauro. Attualmente sono il coordinatore del laboratorio INFN LABEC, dedicato ad applicazioni sia di tecniche IBA sia di Accelerator Mass Spectrometry (AMS) in problematiche relative ai beni culturali e all'ambiente e responsabile nazionale del progetto europeo life+ AIRUSE.
I have got my degree in Physics in 1985. Since 1986, I have been working in Florence at the Physics Dpt, first as a Technologist, then as a University Researcher, presently as an Associated Professor, Faculty of Science, where I teach several basic courses for students of Technologies for the cultural heritage. My research activity deals with experimental nuclear physics, both basic and applied. In the former field, the main activity has been the study of heavy ion beam reactions at energies between few MeV/A and 20 MeV/A, with special reference to the analysis of the fusion-fission and fusion-evaporation reaction mechanisms. I have worked in national and international collaborations mainly at the LNL accelerator, but also at the cyclotrons of the Texas A & M University and SARA in Grenoble. As to the research activity in the field of applied nuclear physics, together with P.A. Mandò I have been one of the promoters of the development of the Florence accelerator lab as a center for IBA analysis in the fields of Cultural Heritage and environmental problems. I have developed in Florence, at the KN3000 accelerator laboratory, an extracted beam facility mainly for PIXE (Particle Induced X-ray Emission, ie, the elemental analysis technique based X induced by ion bombardment on the issue), but also PIGE (Particle induced Gamma-ray Emission) and RBS (Rutherford Backscattering Spectrometry) measurements. This facility was the first in Italy and it is still among the few in the world. Our external beam set-up has evolved significantly from the first measurements made in mid 1987. It took a thorough job to optimize the system for the study of specific problems and to develop the programs for the analysis of the obtained spectra. Starting from 2000, I have promoted the installation in Florence of a new laboratory of INFN (Istituto Nazionale di Fisica Nucleare), fully operational since 2004, dedicated to the IBA and AMS (Accelerator Mass Spectrometry) applications in problems related to the cultural heritage and to environment (special project of INFN named "LABEC"). My group has played a decisive role, in particular, for the success of Ion Beam Analysis techniques in Italy and Europe as standard techniques in the field of cultural heritage, and in this area, thanks to the experience gained since the mid-eighties, it is now considered a world leader. The adopted solutions for our experimental set-up have been widely appreciated abroad, so that copies of the equipment made in Florence have been requested by colleagues of the Tandem accelerator of the Laboratoire de Recherche of the Louvre, from the Chemistry Dpt. Brigham Young University in Provo, UT (USA), from the Centro Nacional de Aceleradores, in Seville, by Josef Stefan Institut, Ljubljana). Many foreign researchers have spent an internship at our laboratory. Among the application I have worked on there are the study of the composition of the materials used for the production of medieval and Renaissance manuscripts (parchment, ink, pigments, rulings used to guide the writing), the study of the composition of ancient inks such as those used by Galileo in the notes he left on the problems of motion (with the aim of contributing to their chronological reordering). This study was carried out by our group in collaboration with the Institute and Museum of the History of Science in Florence, the Max-Planck Institut für Wissenschaftsgeschichte of Berlin and the National Library of Florence. In the last 16 years I have focused my research on the characterization of atmospheric aerosols in areas with different typology (urban, industrial, remote, locations of artistic interest). The IBA techniques are a very effective to quickly analyze a large number of aerosol samples (collected using appropriate samplers). I have developed and optimized IBA techniques, created an external beam set-up specifically designed for the analysis of aerosol samples and developed the use of multivariate analysis statistical models (PCA, APCA, PMF) for the analysis of the data. In addition, I have introduced in Italy the use of continuous two-stage samplers (streaker sampler) for the identification of particulate matter (PM) sources based on the temporal behavior of the elemental composition which can be obtained only with the use of IBA techniques or with the synchrotron light. In this field, our laboratory has become an international benchmark. Recently my group, in collaboration with colleagues of the Department of Chemistry, University of Florence, has developed a procedure for the analysis of the aerosols collected on filters on a daily base that allows to obtain the complete reconstruction of the PM mass, through the combined use of IBA techniques, ion chromatography, HR-ICP-MS and thermo-optical methods for the determination of organic and elemental carbon. This procedure was successfully used in PATOS and PATOS2 projects, promoted by the Tuscany Region with the aim of characterizing particulate air pollution and its sources in different Tuscan areas, both for PM10 (particles with diameter smaller than 10 microns) and PM2.5. I carried out experimental campaigns in various Italian areas, including the first study in Italy of PM1 in urban areas (Genoa, Florence, Milan), at the Global Atmospheric Watch Station of Mt . Cimone (both studies in collaboration with colleagues from the University of Genoa and Milan), in the city of Taranto. I coordinated a campaign for the environmental monitoring at Palazzo Vecchio in Florence. Within the framework of international collaborations which I promoted, I have also studied the composition and the sources of the aerosol in different areas in Spain (Alicante, Elche, Barcelona). Finally, since the combined use of PIXE and PIGE techniques is particularly effective for the study of the composition of the mineral dust, I have used such techniques for the study of desert aerosols (transport phenomena over long distances), Antarctic (trapped in ice cores) and Arctic aerosols. Finally, I coordinated the development of a system for the sample preparation and the AMS measurement for the analysis of the carbonaceous fraction of the aerosol through the measure of radiocarbon (14C). These types of analysis that allow to obtain the percentage of carbon produced by fossil fuel combustion, are among the most innovative in the field of physical methods applied to the study of atmospheric aerosols, but also among the most complex, because of the minimal amount of material available. The whole of my activities has led to over 160 papers published on international journals (with refereeing procedures), to many invited lectures at Italian Institutions and abroad, to several talks at Conferences. Our articles have been repeatedly cited in texts and review articles and, in particular, our facility has been described in detail, as the "standard" reference, in the latest edition of the reference text on PIXE [Particle Induced X-Ray Emission (PIXE), Johansson, Campbell, Malmqvist eds, Wiley, New York 1995, pagg.401-404]. I have been invited as chairman to international conferences (European Aerosol Conference, International Aerosol Conference, PIXE Conference, PM2010). I'm a referee for international journals such as Atmospheric Environment; Journal of Aerosol Science; Nuclear Instruments and Methods B; Chemosphere; Science of the Total Environment; Microchemical Journal; X-Ray Spectrometry; International Journal of Environmental Analytical Chemistry; Analytical Chemistry; Journal of Environmental Management; Atmospheric Research; Environmental Science and Pollution Research. I have been a project evaluator for the Croatian and Luxembourg Ministry of Research. I have been the principal investigator of a research program of national interest (PRIN) with the title "Ion beam analysis, AMS and complementary techniques for the study of environmental physics and Cultural Heritage" financed for 2004-2005 and I have been the principal investigator of an experiment of the Fifth National Committee of INFN. I have been coordinator of a research unit in the 2007 PRIN and in many experiments of the Third National Committee of INFN. I have been the principal investigator of two bilateral projects Italy-Spain and one Italy-Mexico. Now I am responsible for the environmental research group and I am the director of the INFN LABEC Laboratory at Florence and national coordinator of the European Life+ AIRUSE project. I organized national and international workshops on applied and nuclear physics. I have several scientific collaborations with national Institutions (University of Genoa and Milan, the National Research Council, the Regional Environmental Agency) and with international research groups (Centro Nacional de Acceleratores of the University of Sevilla, the Centre for Micro Analysis of Materials (CMAM) of the Universidad Autonoma de Madrid, the University of Birmingham, the University Miguel Hernandez of Elche, the Institute IDAEA of CSIC at Barcellona, the University of Gent). I teach Physics 1 and Physical Methodologies for the study of Cultural Heritage for the degree in Science for conservation and restoration of cultural heritage at the University of Florence. I am member of the PHD School "Science for Cultural Heritage" which is activated at Science Faculty. I had been the supervisor of many degree thesis in Physics or Science for conservation and restoration of cultural heritage and of some PhD students in Physics and Science for Cultural Heritage I have been the coordinator of both a Bachelor and a Masters Degree in Science for conservation and restoration of cultural heritage.
