Sean A. Gallagher is Principal and Director of Sustainable Design at Diller Scofidio + Renfro as well as faculty at Columbia University Graduate School of Architecture, Planning, and Preservation.

Examples of his recent works are the United States Olympic and Paralympic Museum, Microsoft the ‘Square’ project, and Google Pier 57. 

Sean was the design lead for the David Rubenstein Forum in Chicago, which was awarded 2022 Best Tall Tower Worldwide by the International Council of Tall Buildings and Urban Habitats. 

Currently, he is leading the design of the Pardee School of Global Studies in Boston, the first Mass Timber Tower in a major US City. 

Sean believes that a denser carbon neutral urban fabric is key to defining a more sustainable future society.  

He views this future through the lense of being from a small Appalachian mountain community raised by ecologists who taught him how to value and collaborate with nature.

For the last 25 years he’s applied this knowledge to find unique ways to integrate natural systems into the urban fabric.
