Completed his degree in History with specialization in Archeology at FCSH, NOVA University of Lisbon in 2001, an area in which he worked until 2003. Holds a master’s degree in art history at the same university, completed in 2006, where he analyzes the continuity and change in the urban growth of the city of Lisbon, in the first half of the 20th century. In line with his doctorate, concerning the study of the Large Housing Complexes built in the Lisbon region, after the Second World War, completed in 2016, he has worked as a researcher at the Institute of History of Art, seeking to integrate spatial analyzes into the humanities, using space syntax and Geographic Information Systems (GIS). From 2021 onwards his interests focus the study of Archives, on the issue of architectural documents. In this context he completed a Postgraduate Degree in Historical Archive (2021-2022). Along with this Postgraduate, he completed a professional internship at National Archive of Torre do Tombo (from March to June 2022), processing the archive of the architect Luís Benavente (1902-1993), storage there. More recently he integrates the teaching team in a Postgraduate course of Architect Archives (2023-2024), ongoing in the Autónoma University. Although it has regularly published articles based on archival research and primary sources, the specific focus on architecture and landscape architecture archives, in their different historical components, documentary typology, evaluation issues and treatment challenges, has allowed the publication of a relevant work that addresses a set of issues in this regard (Guarda 2022). Other articles, in press, address the complex post-colonial and social housing contexts regarding the production of architecture and landscape architecture in the Portuguese context of the second half of the XX century.
