Sergio Lopez-Pineiro is an interdisciplinary architect who explores voids as socio-spatial phenomena of freedom, diversity, and spontaneity. He is the director of the design studio Holes of Matter and an assistant professor in architecture at the University of Wisconsin-Milwaukee. Lopez-Pineiro is the author of A Glossary of Urban Voids and Typologies for Big Words.
At MacDowell in 2012 Lopez-Pineiro worked on the design for several pavilions, developed as transformations of Fuller's tensegrity structures. In 2023, he worked on “Face-to-Face Encounters,” a project imagining new assembly spaces for Americans of opposing political views to have face-to-face conversations. A previous project that led to the current work was included in Lopez-Pineiro’s book and exhibited at the Harvard Graduate School of Design in 2021 as part of the series “Inside Out.”
