Fábio Miguel Albino Duarte has a master's degree in Early Modern History, which he obtained with a thesis focused on a 17th century inventory of the archive of Counts of Vila Nova de Portimão, a document that shed some light on the relationship Portuguese nobility kept with their own records. While graduating in History at the Faculty of Social Sciences and Humanities, Nova University of Lisbon, he took part in two projects, coordinated by Professor Maria de Lurdes Rosa and Postdoctoral Researcher Rita da Nóvoa, in which he and his colleagues transcribed the 19th century archival inventories of the Houses of Viscounts and Counts of Lapa and Marquises of Castelo Melhor. Not only did those experiences enable him to contact with some of the Portuguese and Spanish experts in the flourishing subject of Archival History through attendance in various scientific meetings, but also made him realize that archives, whether private or public, aren't just repositories of information. As living organisms, their multiple organizations reflect the dynamics of History itself, and the thoughts of those who decided to preserve and destroy documents. To deepen his knowledge of this matters, Fábio did an internship at Torre do Tombo National Archive where he described documentation from the archive of Marquises of Fronteira and Alorna. As he was writing his thesis, he spent a semestre in Madrid, in 2019, attending classes and researching in Spanish archives. Since 2022, he is a research fellow in VINCULUM Project, which is coordinated by Professor Maria de Lurdes Rosa.
