Jeffrey Mansfield is a design director at MASS Design Group, whose work explores the relationships between architecture, landscape, and power. Currently, Mansfield is researching how Deaf schools and other Deaf Spaces emerged as sites of cultural resistance in the nineteenth and twentieth centuries, and is a recipient of a Graham Foundation grant and the John W. Kluge Fellowship at the Library of Congress for this work. At MASS, he leads the Restorative Justice Design Lab, leveraging the design process to advocate for mass decarceration and works on a number of design projects, exhibitions, and publications, including MASS Design Group’s first monograph, Justice is Beauty (The Monacelli Press, 2019).

Mansfield's work has been published in the Cooper Hewitt Design Journal, AD, and Tacet and exhibited at MoMA PS1, Bergen Assembly, São Paulo Biennale, Sharjah Biennial, and Tallinn Art Hall. He holds a Master of Architecture from the Harvard Graduate School of Design and an AB in Architecture from Princeton University. Deaf since birth, Mansfield attended a deaf school in Massachusetts, where his earliest intuitions about the relationship between architecture, society, and power emerged.
