I completed my doctoral thesis (PhD) at Keele University (United Kingdom) in 2014/15, researching silicic volcanism and the emplacement and textural characterisation of young silicic lava flows in the Aeolian Islands (Italy). In October 2015, I started as a Research Fellow (Grade 6) at the School of Geosciences, University of Aberdeen, delivering research and associated activities in the School of Geosciences on the “Tellurium and Selenium Cycling and Supply” project. I was previously employed as a Geological Consultant for Tactical Environmental Response Ltd and GP Resource Mining Ltd (mineral exploration).
