Dr. Tozzi graduated in Physics at Sapienza University of Rome (Italy) in 1999, with a thesis on the nonlinear analysis of the geomagnetic field secular variation recorded during XX century. Then, in 2004, she obtained a PhD at the University of Bologna "Alma Mater Studiorum"; during this period she extended and went more in depth in the investigations performed for graduation. In the following years she worked as a temporary research scientist at Istituto Nazionale di Geofisica e Vulcanologia (INGV) focusing on topics concerning the Earth’s magnetic field of internal origin as for instance geomagnetic jerks, widening her knowledge and command of geomagnetic field models as well as of mathematical methods (e.g. bispectral analysis, natural orthogonal components and empirical mode decomposition) as tools to extract information from geophysical time series. Since December 2010, Dr. Tozzi has a permanent research position at INGV and the focus of her studies has gradually moved from internal geomagnetism to solar-terrestrial interactions and space weather. She has extensively worked with Swarm magnetic data (e.g. in the ESA INTENS project), but has also continued analysing magnetic data from ground observatories to investigate geomagnetically induced currents. In the framework of MARGE, Dr. Tozzi participates to the activities of Tasks 2, 3, 4 e 7 and leads Task 5.
