Mark Wigley, pictured, is stepping down as Dean of Columbia University’s Graduate School of Architecture, Planning, and Preservation, a role that he has held for the past decade. Wigley, a New Zealand–born architect and author, will continue his position through the academic year. Columbia’s president, Lee C. Bollinger, made the announcement through email, affirming that “in every context, [Wigley] has represented the School and the institution in ways that make us all proud to be part of such a vibrant place.” (Photo: Courtesy Columbia)
