I started off doing a Bachelor’s degree in Geology at Università di Milano-Bicocca, focusing on geochemistry and marine geology. I attended classes on geobiology and ecology of underwater ecosystems, in particular on the coral reef environments. In 2007 I participated to a stage of tropical marine ecology in Sharm el Sheik (Egypt).
For my dissertation I arranged a cooperation between the department of Geology and Archaeology; the main aim was to date with the thermoluminesce method Greek furnaces from the Metaponto area.
For my Masters I moved to the University of Western Australia, Perth, and continued developing skills on geochemistry and geochronology. I followed two projects there; the first was aiming to determine a new apatite age standard for U-Th/He thermochronology. In the second year instead I was involved in a part of a bigger project regarding the evolution of Cape Fold Belt and Karoo Basin (South Africa) in collaboration with the University of Liverpool. After graduating in 2012 I moved back to Europe.
In October 2013 I started a PhD in the GLANAM network at Oban, Scotland.

Previously, numerous studies have been undertaken both onshore and offshore to decipher the morphological and sedimentological record in order to better constrain the limits and duration of the British-Irish Ice Sheet (BIIS) (Ballantyne et al. 2009, Bradwell et al. 2008b, Clark et al. 2011, Dunlop et al. 2010, Howe et al. 2012,O’Cofaigh et al. in press). Late glacial ice sheet dynamics have been revealed to be far more rapid and responsive to climatic amelioration than had previously been considered.
Notable in this debate has been the evidence that has been obtained in the inshore and, to a lesser extent, offshore on the UK continental shelf. Here new geomorphological data, principally multibeam echo sounder (MBES) data has provided imagery of previously unseen features interpreted as being glacial in origin.
In the wake of these new discoveries this projects aims to investigate the extent, timing, growth and final disintegration of the BIIS across Western Scotland. This area of particular interest for the development of the glaciated North Atlantic margin has been generally neglected in past studies, especially across the mid-outer shelf, which constitutes a missing part in the jigsaw of the reconstructed BIIS during the last ~20.000yrs.
We aim to mainly focus on geomorphological analyses of MBES data collected in the Firth of Lorn and Sea of Hebrides; a study of features as moraines, glacial lineations and drumlins will provide important clues on the dynamics and maximum extension of the sheet.
Subsequently we will examine the geometry and composition of the shelf sediment infill, aiming to constrain the influence of ice retreat on depositional environments using multi-element geochemical (14C and 210Pb dating) and sedimentological techniques. Such an investigation will also give retrospective information on the sources for these sediments, hence more indications on ice configuration. Ultimately we aim to provide a model of deglaciation for the western sector of the BIIS.
