“Structural Instabilities: History, Environment, and Risk in Architecture” is a two-day, five-panel symposium that explores how the instabilities of 21st-century architecture link to architectural histories of gender, race, environmental change, political revolution, colonialism, feminism, and more. Felicity Scott, professor of architecture at Columbia University, delivers the keynote, with concluding remarks from Brett Steele, dean of UCLA’s School of the Arts and Architecture.
