Pedro Valério obtained the degree in Chemical Engineering in 1994 at Instituto Superior Técnico (IST), finished the MSc in Chemistry Applied to Cultural Heritage in 2005 at Faculdade de Ciências da Universidade de Lisboa (FC-UL) and completed the PhD in Conservation and Restoration in 2012 at Faculdade de Ciências e Tecnologias da Universidade Nova de Lisboa (FCT-UNL). Presently, Pedro Valério is an Auxiliary Researcher at Department of Nuclear Sciences and Engineering of Instituto Superior Técnico (IST) and a researcher of Centro de Ciências e Tecnologias Nucleares (C2TN). Pedro Valério published 47 articles in peer-reviewed international scientific journals and is the author or co-author of more than 100 articles in national scientific journals, book chapters and conference papers. Cultural Heritage and Archaeometallurgy comprise the main research areas with special emphasis in the study of metal production, use and circulation in communities inhabiting the Portuguese territory from the Chalcolithic to the Roman Empire. Archaeometallurgical research includes the characterisation of metal ores, production remains (crucibles, slags, tuyeres, prills, moulds and ingots) and finished artefacts (weapons, tools and ornaments). The chemical composition, microstructural characteristics, manufacturing features and Pb isotope signature are correlated with source, function and chronology to establish the metallurgical knowledge of ancient communities, metal trade routes and technological innovations concerning the copper-based, silver and gold alloys. Recent focus of such research includes "The evolution of arsenical copper alloys in Bell Beaker and Bronze Age communities", "The Phoenician impact on the bronze and gold technologies in SW Iberian Peninsula", "The sources of copper to SW Iberian Peninsula during the 1st millenium BC" and "The provenance of copper and lead of southern Portugal during the Iron Age".
