Ilenia Arienzo is researcher at INGV, OV; she has a PhD in Geophysics, awarded in 2006 at the Alma Mater Studiorum University of Bologna. The title of the thesis was Magmatic processes and their timescale in the Campanian Ignimbrite magma chamber combining U–Th and Sr–Nd systematics. Since 2002 to 2012 she has been PhD student and Post–PhD student at the Istituto Nazionale di Geofisica e Vulcanologia (INGV), sezione of Napoli, and at the University Federico II of Napoli. Since 2012 to today she has been researcher at the Istituto Nazionale di Geofisica e Vulcanologia, sezione of Napoli. Since May 2014 she has been responsible of the Radiogenic Isotope Laboratory of the Istituto Nazionale di Geofisica e Vulcanologia, sezione of Napoli and since January 2013 she has been qualified as assistant professor (professore di II fascia). Her main research interests are in Geochemistry, isotope geochemistry and petrology. The research activity of the principal investigator has been focused at defining the structure and the evolution of the magmatic feeding systems of the Campi Flegrei caldera, Ischia and Procida volcanic islands (South Italy) and investigating magma chamber processes (e.g. fractional crystallization, crustal contamination and mingling/mixing among distinct magmas/magmatic components). The depth of magma crystallization have been also established by studying the volatiles of melt inclusions entrapped in minerals by FTIR spectroscopy. Furthermore, isotope investigations (Sr, Nd, Pb) have been performed on rock samples from a bore–hole in the area of Camaldoli della Torre (Vesuvian area, Naples) in order to study the most important eruptions occurred and for defining magma chamber processes. In the last few years, in collaboration with researchers from CNR and INGV, Sr and Nd isotopes have been proposed as useful tools for correlating proximal and distal tephra erupted from Italian volcanoes (e.g. Colli Albani, Sabatini and Campi Flegrei). By performing geochemical and isotopic investigations on products from Mt. Etna and Stromboli volcanoes, from the Ethiopian rift volcanoes and from Piton de la Fournaise volcano, it has been possible to contribute in deepen the knowledge on the feeding systems of these volcanoes. In the last year principal investigator have measured Sr isotopes on human teeth and bones for human mobility studies. Recently, Sr and Nd isotopes have been used, in collaboration with researchers from the university of Napoli, as tools for assessing the provenance of ceramic materials for archeometry studies. In the last year Sr isotope ratios have been measured, by the principal investigator, on water samples from Roccamonfina volcano, for water-rock interaction studies and on groundwater samples from Mt. Etna volcano for tracing the circulation of groundwater. Since 2001 she has been responsible of different projects and she has participed in some research projects.
