Sergio Lopez-Pineiro is an interdisciplinary architect, whose work explores voids as socio-spatial phenomena of freedom, diversity, and spontaneity.

Lopez-Pineiro is the director of Holes of Matter, a design studio operating at the intersection of architecture and landscape. It aims to look at the mutual influence between sociocultural forces and spatial organizations, and imagine existing and potential gaps to redefine relations between individual and collective forms of life. Lopez-Pineiro is a lecturer in landscape architecture at the Harvard Graduate School of Design, where he teaches design studios and theory seminars on architecture and landscape with a focus on the public nature of the built environment. He has previously held the 2006-07 Reyner Banham Fellowship at the University at Buffalo and the 2014-15 Daniel Urban Kiley Fellowship at Harvard University.

Lopez-Pineiro is the author of the volume A Glossary of Urban Voids (Berlin: Jovis, 2020). His projects and texts have been published internationally by a+t, MAS Context, Bracket, arq: Architecture Research Quarterly, Places, 2G, and others, and his work has received support from the New York State Council on the Arts (NYSCA) and MacDowell. Lopez-Pineiro is a licensed architect in Spain. He trained at the Escuela Técnica Superior de Arquitectura de Madrid (ETSAM) and received his Master of Architecture degree from Princeton University, where he was awarded the Suzanne Kolarik Underwood Prize. He previously worked at No.mad in Madrid and Foreign Office Architects in London.
