Alexandra Castro holds a degree in Architecture from the Faculty of Architecture at the University of Porto (FAUP, 2002). Since 2009, she has held a Master’s degree in Methodologies of Intervention in Architectural Heritage from the same institution (FAUP, 2009). In 2023, she completed her PhD in Architecture at FAUP with the dissertation "The Hidden Geometry of the Architecture of Herzog & de Meuron, Digital Tools and Design Practice". The research, carried out in close collaboration with the Basel-based office, aimed to explore the relationship between geometry and architecture in the work of these Swiss architects, focusing specifically on the impact of digital tools on their design practice. She is currently an Invited Assistant Professor at the Faculty of Architecture of the University of Porto, where she has been teaching the course “Geometry and Architecture” since 2014. In 2011–2012, she was an Invited Assistant Professor at the School of Architecture, Art and Design of the University of Minho, where she coordinated and taught the first-year course “Geometry” of the Integrated Master in Architecture. She began her academic career as a teaching assistant at IUAV – Istituto Universitario di Architettura di Venezia, in the course “Design Studio II”, coordinated by Professor Paolo Merlini, during the academic year 2002–2003. In 2013, Alexandra Castro joined the Centre for Studies in Architecture and Urbanism (CEAU) at FAUP, as part of the research group ATPH – Architecture: Theory, Project and History, where she has been a Full Member since 2024. Her research interests include geometry, drawing, digital modelling, architectural representation, and design practice. She is the author of several articles published in scientific journals, book chapters, and conference proceedings, and regularly presents the outcomes of her research at specialised conferences through oral communications. In 2010, together with architect Nicola Natali, she founded the architecture practice Castro Natali, based in Porto. Since its inception, the studio has developed projects for both public and private sectors in Portugal and abroad, in the fields of culture, heritage rehabilitation, public space, and housing. More recently, their work was awarded first prize in the international two-stage competition for the design of the San Bernardino Primary School in Caravaggio (Italy), developed in collaboration with Studio Bombasaro. Notable projects include the São Pedro da Cova Urban Park in Gondomar (2020–2023); the Rehabilitation of the Church of Borba de Godim and Surrounding Spaces, in Felgueiras (2019–…); and the Extension of the Mòcheno Cultural Institute, in Trento, Italy (2008–2014).
