oma-logo OMA is an international practice operating within the traditional boundaries of architecture and urbanism. AMO, a research and design studio, applies architectural thinking to domains beyond.  OMA is led by nine partners – Rem Koolhaas, Ellen van Loon, Reinier de Graaf, Shohei Shigematsu, Iyad Alsaka, Chris van Duijn, Ippolito Pestellini Laparelli, Jason Long, and Managing Partner-Architect David Gianotten – and maintains offices in Rotterdam, New York, Hong Kong, Beijing, Doha, Dubai and Perth.
