Vishaan Chakrabarti is a registered architect and the founder of PAU. Simultaneously, Vishaan is an Associate Professor of Practice at Columbia University’s Graduate School of Architecture, Planning & Preservation (GSAPP), where he teaches architectural design studios and seminars on urbanism. His highly acclaimed book, A Country of Cities: A Manifesto for an Urban America (Metropolis Books, 2013), argues that a more urban United States would result in a more prosperous, sustainable, joyous, and socially mobile nation. Of the book, the Toronto Globe and Mail wrote: “In the world of urbanism and planning, there’s been a barrage of recent books on similar themes…but Mr. Chakrabarti has written maybe the most useful one, a polemic in favor of city living that makes the stakes clear.” Bruce Katz and Jennifer Bradlee named A Country of Cities one of the top ten books of 2013 in the Huffington Post.
