Karen Lewis is an Associate Professor of Architecture at the Knowlton School of Architecture at The Ohio State University, where she has taught since 2009. She holds degrees from Wellesley College and the Harvard Graduate School of Design.
Her work begins with a proposition: that the tools of architecture — spatial analysis, material attention, the reading of what a site withholds as much as what it reveals — can generate historical knowledge that conventional documentary methods cannot reach. She approaches the archive the way an architect approaches a building: not as a repository to be surveyed from a fixed vantage point, but as a system to be entered, moved through, and reconstructed from within.
This is, at its core, a practice of assembly. Working at the intersection of historical cartography, data visualization, and forensic spatial analysis, she brings disparate primary sources into proximity — maps, survey records, testimonial accounts, physical traces — and attends to what emerges from the encounter. The relationships she finds are rarely legible until the materials are held together; the argument lives in the arrangement.
Her current research focuses on the spatial history of the Underground Railroad, asking what the built environment can tell us about a freedom network designed to leave no trace. She is drawn, more broadly, to systems: to the grammar of cartography, to typography as structure and meaning, to the three-dimensional logic of how information organizes itself in space. Her book Graphic Design for Architects (Routledge, 2015) has become a standard text in the field; a second edition is forthcoming.
