Francesco Riggi is full professor in Experimental Physics at the Department of Physics and Astronomy, University of Catania. 

Teaching activity
Over the years his teaching activities included lectures on Experimental Physics for students in Biology (1991-2001), General Physics (2001-2007), Scientific Museology (2002-2005), High Energy Nuclear Physics (2005-2012), Physics Laboratory for 3rd year physics students (2009-present), Experimental Methods in Nuclear Physics (2012-present).
As a part of his teaching activity he has acted as supervisor for several degree, master and PhD theses in Nuclear and General Physics. He is also involved in the post-degree program for high school teachers and for PhD students.

Research activity
He has carried out research in Experimental Nuclear Physics since 1974: at the beginning of his activity in the field of low and intermediate energies, in various Laboratories over the world (GANIL and CEA Saclay, France), Michigan State University (USA), Moscow (Russia), TSL Uppsala (Sweden), Athens (Greece), Daresbury (United Kingdom) with large solid angle detectors and magnetic spectrometers. 
Since 1995 he is involved in researches carried out at CERN in the domain of ultra-relativistic heavy ion collisions, joining the NA57 experiment at SPS (especially concerned with the study of strangeness production) and the ALICE Collaboration at LHC (A large multipurpose detector for the study of heavy ion collisions at the highest available energies). Within the ALICE Collaboration he has been and is involved in the construction and use of the silicon pixel detector of the Inner Tracker System and in the electromagnetic calorimeter. 
He is also collaborating with the EEE (Extreme Energy Event) Project, to develop an extended network of cosmic ray telescopes in the italian schools, and more recently has taken the responsibility for the construction of a large area muon detector employing the muon tomography technique for the inspection of container (The Muon Portal Collaboration). 
He is author of about  500 scientific papers published in international physics journals. 

Organization activity
He is member of the Collaboration Board of the ALICE experiment, Team Leader for the Catania site, and member of the Executive Committee of the EEE Collaboration. He has also been organizer of Workshops and international Meetings, and acts as referee for several Journals in Physics. 
Scientific Coordinator of the PhD School in Physics of the University of Catania (2005-2016). Involved in dissemination and outreach activities, he also collaborates to various newspapers and magazines.

 

Francesco Riggi was born in 1951. He received his master degree in Physics from the University of Catania in 1974. From 1975 to 1979 he was a fellow of the CSFN (Sicilian Center for Nuclear Physics). In 1980 he got a permanent position at the University of Catania as a Researcher, then as Associate Professor and Full Professor (since 2001) in Experimental Nuclear and Particle Physics at the Department of Physics and Astronomy.

Scientific Research

   He has been working for about twenty years (1974-1995) in the field of nuclear physics at low and intermediate energies, participating to experiments concerned with three-body final state nuclear reactions, subthreshold pion and kaon production at intermediate energies, and heavy ion collisions with large multidetectors. Since 1995 he joined the field of ultra-relativistic heavy ion collisions at CERN, within the NA57 Collaboration, devoted to the study of strangeness enhancement in high energy collisions, and later in the ALICE Collaboration, a large (>1000 participants) international experiment devoted to the study of nuclear matter under extreme  density and energy density conditions at the Large Hadron Collider (LHC). Within the ALICE Collaboration he has been involved with a research team in Catania in the construction of the Silicon Pixel Inner Tracker System (ITS) and of the Electromagnetic Calorimeter. He is also presently involved  in the upgrade activities of this experiment. The physics items of interest in heavy ion collisions with the ALICE detector are concerned with the study of strangeness production as a signature of the Quark Gluon Plasma formation and with the investigation of short lived resonances.

   He has also been  actively carrying out research in the field of Cosmic Ray physics, where he is a member of the EEE Collaboration (an extended network of cosmic ray telescopes built and operated by high school teams) and in various applications of the cosmic ray radiation, concerned with muon tomography techniques, where he has leaded a four-years Project for the construction of a real size prototype detector (3 x 6 x 7 m3),  able to inspect the interior of a cargo container to signal the presence of high-Z fissile materials.

   He has also contributed to other scientific areas of research, in collaboration with the Chemistry Department, including the study of electron paramagnetic resonance (EPR) of Transition Metal complexes,  and  the use of molecular mass spectrometry with heavy ions.

   He is author or coauthor of about 500 peer-reviewed scientific papers in all such areas (see attached list of the most recent papers) and has contributed to several International Conferences,  with invited and contributed talks. His recent (July 2018) H-index (Hirsch) is  59.

   During his scientific career, he has spent various periods abroad, collaborating with many international Institutions and Laboratories: GANIL, CEN-Saclay and Orsay (France), Monash University (Melbourne, Australia),  Tandem Laboratory (Daresbury, UK),  Demokritos Centre (Athens, Greece), Ruder Boskovic Institute (Zagreb, Croatia), TSL Laboratory (Uppsala, Sweden) INR (Moscow, Russia), Michigan State University (USA), CERN, DESY (Germany). He is associated to various scientific Institutions and Societies since many years (CSFN, CERN, SIF, Centro Fermi,..)

   He has been team leader for various research projects, funded by the National Institute for Nuclear Physics (INFN) and the Italian Minister for Education and Research (MIUR), concerned with nuclear and applied physics. He has also been responsible for a Project on Muon Tomography (2011-2015). He acts as referee for several international Journals in Nuclear and Applied Physics and has been organizer or member of the Editorial Board for various international Conferences and Workshops.

University Teaching  Activity

As a professor at the Department of Physics and Astronomy of the University of Catania, he has been teaching Experimental Physics since more than 35 years, for students in Biology, Chemistry, Geophysics and Physics Curricula. Specific courses in Physics (Bachelor, Master and PhD Curricula) over the past years included: High Energy Nuclear Physics, Experimental Methods in Nuclear Physics, Modern Physics Laboratory Course, Cosmic Ray Physics Laboratory,…). He has been supervisor of more than 50 master and PhD theses, and coauthor of a textbook in experimental physics. As a part of the teaching activity in Physics he has published several papers on educational experiments at various levels (high school and undergraduate) in peer-reviewed scientific Journals (see attached list of educational papers). He has also been lecturer for two interdisciplinary courses: “History of Physics” and “Scientific Museology” within the Faculty of Science of the University of Catania. For about ten years he has also been a member of the Faculty of Theology in Catania, where he contributed giving lectures on Epistemology, History and Philosophy of Science.

It was suggested not to insert any link to a pdf file containing the  list of publications, which could produce a much better result in terms of editing and presentation of the complete list of publications.
