Sergio Lopez-Pineiro is an interdisciplinary architect, whose work explores voids as socio-spatial phenomena of freedom, diversity, and spontaneity. He is the director of Holes of Matter, a design studio in architecture and landscape, and 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. Lopez-Pineiro is the author of A Glossary of Urban Voids.
Lopez-Pineiro dedicated his time at MacDowell to design spatial fields (continuous, homogeneous, and non-hierarchical distributions of elements) as the means to imagine space emptied of preexisting socio-cultural structures. In particular, he spent time designing tensegrity structures, which are structural configurations that find balance by mixing up and distributing different types of forces.
