![]() Main scientific assignements and related activity: Core member of the Relativity and Reference Frame Working Group (RRFWG) of the Gaia mission (ESA). I cover the role of national coordinator for the outreach Italian participation in Gaia and responsible for the science dissemination project entitled " The History of Photons ". ![]() Outreach programs have been instituted within the context of the Gaia. quasars astrometric interpretation of sub-stellar objects (low mass star and brown dwarf, in the solar system neighborhood) from ground observations. Briefly, my activity has been focused on: refinements of the RAMOD models, a family of general relativistic models of increasing intrinsic accuracy, suitable for the interpretation of high precision astrometric data within the precepts of General Relativity, and its specialization to the Gaia mission context for the validation of the baseline model (GREM) application of the theory of measurement in General Relativity to Astrophysics and, in particular, to the inverse light ray tracing problem tests on General Relativity, such as light deflection due to the giant planets and microlensing effects legacy of fundamental physics to relativistic astrometry and local cosmology new relativistic effects, in particular those detectable by astrometric observations space-time navigation, relativistic transformations between the Celestial Coordinate Reference Systems (IAU resolutions) and link to the Celestial Reference Frame, i.e. This has required developing mathematical skills able to tackle the complexity of the inverse ray-tracing problem in curved space-time: for more than a decade I am one of the pioneers of the validation relativistic model for the data of the Gaia astrometric mission. Part of my activity was also dedicated to the appropriate comparison of fully general relativistic model and approximated ones with particular emphasis on the reconstruction of stellar light trajectory. Within Gaia I was a core member of the Relativity and Reference Frame Working Group (RRFWG) of Gaia, and, at the present, I am responsible of the workpackage Local Relativistic tests and of the workpackage Theoretical comparison between relativistic models (Development Unit "Relativistic Models and Tests") within the context of the Coordinate Unit 3 (CU3) of the Gaia Data Processing and Analysis Consortium (DPAC). Mignard on the assessment of the relativity experiment close to Jupiter's edge. ![]() ![]() I was also Poincaré Fellow at the Observatoire de la Côte d'Azur (INSU -CNRS / OCA ), starting the work with Dr. de Felice (University of Padua) and in close collaboration with the Astrometric Group at the Observatory of Turin. The need of a relativistic model suitable for the reduction of high precision astrometric data for the Gaia mission (ESA, launched on December 2013) and for new gravitational tests, its validation on realistic simulations has been the main subject of my research activity carried out since my Ph.D. in Space Science and Technology, University of Padova, Italy (2003) Laurea in Physics (grade: 110/110 cum laude), Università degli Studi di Torino, Italy (1998) Visiting Scholar, University of Missouri, Columbia MO, USA (2001) Positions Held: From 2008 Researcher, permanent position, INAF – Osservatorio Astrofisico di Torino 2005 – 2007, Fixed term researcher, INAF – Osservatorio Astrofisico di Torino, Juanuary 2004 - February 2005, Post-Doctoral Poincaré fellowship, Astronomical Observatory of Nice (OCA/CNRS/INSU, France) Scientific biography I have a permanent position as researcher astronomer at the Observatory of Torino- INAF.
