Joshua Prince-Ramus is the founding principal and president of REX, where he leads the design of all projects. Joshua was the founding partner of OMA New York—the American affiliate of the Office for Metropolitan Architecture/Rem Koolhaas—until he rebranded that firm as REX in 2006. While REX was still known as OMA New York, Joshua was partner-in-charge of the Seattle Central Library and the Guggenheim-Hermitage Museum in Las Vegas, among many other cultural projects.

A former member of the TED Brain Trust, Joshua has shared REX’s design methodologies at the TED2006 and TEDxSMU conferences. He is the most recent recipient of the Marcus Prize, bestowed upon architects "on a trajectory to greatness.” Joshua has been credited as one of the “5 greatest architects under 50” by The Huffington Post, one of the world’s most influential young architects by Wallpaper*, and one of the twenty most influential players in design by Fast Company; he was also listed among “The 20 Essential Young Architects” by ICON magazine and featured as one of the “Best and Brightest” by Esquire magazine.

Joshua is a frequent contributor to architectural academia, convinced that—if architecture is to evolve—professionals have a responsibility to improve the profession from within. He has been Eero Saarinen Visiting Professor at Yale University and Cullinan Visiting Professor at Rice University, and has been a visiting professor at Columbia University, Harvard University, the Massachusetts Institute of Technology (MIT), and Syracuse University. He lectures frequently in universities and symposiums around the world.

Joshua holds a Master of Architecture from Harvard University, where he earned the inaugural Araldo Cossutta Fellowship and the SOM Fellowship, and a Bachelor of Arts in Philosophy with distinction in the major, magna cum laude, from Yale University. He is a registered architect in the U.S. and the Netherlands, and is NCARB certified.
