REX’s Founding Principal, Joshua leads the firm’s think-tank of diverse professionals and remains intimately involved in all the office’s work. In 2016, Joshua was the first American recipient of the Marcus Prize, the $100,000 biennial, international architecture award conferred by the Marcus Corporation Foundation and the University of Wisconsin. He has also been credited as one of the “5 greatest architects under 50” by HuffPost; the world’s most influential young architects by Wallpaper*; the twenty most influential players in design by Fast Company; “The 20 Essential Young Architects” by ICON magazine; and the “Best and Brightest” by Esquire. In 2020, Joshua was honored by the experimental performance company STREB with their Action Maverick Award.

Joshua has been Eero Saarinen Visiting Professor at Yale University, Cullinan Visiting Professor at Rice University, and a visiting professor at Columbia University, The Cooper Union, Harvard University, Massachusetts Institute of Technology, and Syracuse University. An early member of the TED Advisory Board, Joshua shared REX’s design methodologies at TED and TEDxSMU conferences, and lectures frequently at universities, cultural institutions, 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, magna cum laude with distinction in the major, from Yale University. He is NCARB Certified and a registered architect in states throughout the U.S. and Australia, as well as in The Netherlands.

Joshua was a founding partner of OMA New York in 2001 and remained its principal until he re-branded the firm as REX in 2006. In that time, he was partner-in-charge of all the firm’s projects, including the Guggenheim-Hermitage Museum in Las Vegas and the Seattle Central Library, hailed by The New York Times’ architecture critic, Herbert Muschamp, as “the most exciting new building it has been my honor to review in more than 30 years of writing about architecture.”



Alysen is a director at REX, co-managing the office with Joshua Ramus. She has been leading the design team for the Ronald O. Perelman Performing Arts Center at the World Trade Center (nearing completion) since its competition stage in 2014. In this highly complex project on one of New York’s most venerated sites, Alysen has had to navigate extensive below-grade considerations (including the foundations of a previous design, high-security truck circulation, and layers of subway and train lines); stringent acoustic, terrorist, and flood design criteria; and the desires, timelines, and infrastructural needs of numerous stakeholders (including The Perelman Center, the Port Authority of New York & New Jersey, the City of New York, the New York Police Department Counter-terrorism Bureau, the Lower Manhattan Development Corporation, and the U.S. Department of Housing and Urban Development). Alysen was also a project leader on the re-cladding and renovation of Five Manhattan West, a Brutalist landmark straddling New York Penn Station’s rail yard; the Necklace Residence on New York’s Long Island; and the Wakefield School Performing Arts Center in Virginia.

Prior to joining REX in 2012, Alysen worked on a wide range of architectural projects with several world-renowned architectural firms. At Bjarke Ingels Group (BIG) in Copenhagen, Denmark, she worked on the House of Culture & Movement in Frederiksberg, Denmark and TEK, a mixed-use proposal including retail, hotel, and exhibition space in Taipei, Taiwan. While with Zago Architecture in Los Angeles, she worked on the proposed development of a multi-unit social housing complex as part of Foreclosed: Rehousing the American Dream, a MoMA commissioned project to explore new architectural possibilities for cities and suburbs in the aftermath of the 2008 foreclosure crisis.

Alysen holds a Master of Architecture from the University of Illinois at Chicago, as well as a Bachelor of Arts in Art & Design, with honors, and a Bachelor of Arts in Journalism, both from the University of Iowa.



With REX since 2011, Adam is a senior associate and has been core to the firm’s design and intellectual rigor for more than a decade. He is currently running The Lindemann Performing Arts Center at Brown University in Providence, Rhode Island (nearing completion) and two mixed-use towers on Perth’s Elizabeth Quay in Australia (under construction). Adam is an expert in performing arts centers, having served as project leader for REX’s designs of the Shenzhen Opera House, the Komische Oper Berlin Expansion, the Wakefield School Performing Arts Center in Virginia, the Mercedes-Benz Future Lab & Museum in Stuttgart (which houses several performance components), and—until leading the design of The Lindemann Center—the Ronald O. Perelman Performing Arts Center at the World Trade Center with Alysen Hiller Fiore. He was also a key team member for the Yongsan International Business District “Project R6” Tower in Seoul, South Korea and the transformation of Five Manhattan West in New York.

Adam graduated from The Ohio State University with a Master of Architecture and a Bachelor of Science in Architecture, both with honors. Adam is NCARB Certified and licensed in New York.



Having joined REX in 2014, Raúl is a senior associate at REX currently leading 205 North Quay, a 37-story office tower in Brisbane, Australia; the 4,050 m² (43,600 sf) Necklace Residence on New York’s Long Island; and a luxury apartment in Manhattan, all under construction. In addition, Raúl contributed his expertise in the design and detailing of complex interiors to projects such as 2050 M Street, Five Manhattan West, the Ronald O. Perelman Performing Arts Center at the World Trade Center, The Lindemann Performing Arts Center at Brown University, Elizabeth Quay, and the Calvin Klein Voyeur House Singapore.

Prior to joining REX, Raúl worked at Vicens + Ramos Architects in Madrid, managing the design of several high-end residential estates in Europe and America, as well as institutional and religious buildings such as the Ice Pavilion at the Zaragoza International Exhibition 2008, a health complex in Coslada, and the Parish Church of Solace in Cordoba, all in Spain.

Raúl was Associate Professor at Universidad Nebrija in Madrid and Lecturer in Architecture at Universidad Politécnica de Madrid (UPM). A licensed architect in Spain, Raúl holds a Ph.D., summa cum laude; a Master of Architecture, for which he was awarded the Alejandro de la Sota Prize for best thesis; and a Bachelor of Science in Architecture & Urban Planning, all from UPM. He has written several articles in international academic journals and has authored an architectural travel guide published by Mairea Libros.

Raúl is a proud member of the LGTBQIA+ community and leads REX’s continuous effort to uphold values of diversity, equity, and inclusion.
