  • Short CV: I studied Physics in Rome, at the E. Amaldi University of Roma Tre, where I graduated in Nuclear and Sub-Nuclear Physics in January 2008. I moved immediately after to France where I started a Doctorate in Particle Physics at the Paris 7 University, in the APC laboratory (AstroParticule et Cosmologie). In Paris, I worked on a new generation experiment, MEMPHYS, dedicated to the measurement of neutrinos, building a 8 tons prototype of water Cherenkov  detector and studying a new electronic readout system (ParisRoc). After my doctorate, I moved back to Rome, with research grants at the Centro Fermi, Sapienza and INFN, and I joined the ARPG group (Applied Radiation Physics Group). I immediately started working in a new field of research for me: physics applied to medicine. In particular, we measured the flux of charged and neutral particles produced in particle therapy. With the ARPG group I did many measurements campaigns, data analysis and small R&D projects, up to the design of a new detector (Dose Profiler), a monitor of range and dose for therapeutic beams for the CNAO Center of Adrotherapy. In 2015 I also started working as Principal Investigator on an innovative tracker dedicated to the characterisation of the ultrafast neutrons produced in particle therapy: MONDO. In addition to the realisation of the detector with scintillating fibres, I worked in collaboration with FBK to develop a silicon sensor (based on SPAD) specifically dedicated to this application. MONDO will be the first neutron tracker in the energy range of interest for particle therapy. From 2015, together with a small group of colleagues, I developed a new way to detect particles with GEMs: it is a triple GEM detector that exploits a sCMOS camera to take images of the particles’ tracks. This new detector has been used in different applications, for example by the CYGNO experiment for the search for dark matter, and proposed for beam monitoring purposes in particle therapy. During these years I have studied, developed and characterised new scintillators useful in multiple research fields, for the most promising ones we proposed a patent (Sapienza and Centro Fermi). In recent years I have become part of the collaboration of the FOOT experiment, dedicated to the measurement of the fragmentation of the elements constituting the human body (C, O, H). These measures will serve to evaluate the RBE (Relative Biological Effectiveness) of protons in particle therapy and to evaluate the shielding materials for radiation protection in space travel. Since 2019 I am a researcher at the Centro Fermi. My research is mainly devoted to the development of innovative detectors in medical applications.
