Sarah Dunn co-founded UrbanLab with Martin Felsen. Sarah is a Professor in the School of Architecture at the University of Illinois at Chicago and also teaches advanced studios at Columbia's Graduate School of Architecture, Planning and Preservation. After working at the Office for Metropolitan Architecture (OMA) in Rotterdam, she and partner Martin Felsen established UrbanLab, a collaborative architecture and urban design firm. UrbanLab strives to respond to the complexity, growth and unintended consequences of the modern city by developing a catalogue of architectural, infrastructural and urbanistic design strategies, in particular examining natural and artificial systems underpinning the built environment. Built work to date includes mixed-use commercial buildings, housing, houses, restaurants, art galleries, large-scale resilient infrastructural projects, recreational landscapes, and cities.
