Nikos Angelos Salingaros (Greek: Νίκος Άγγελος Σαλίγκαρος; born 1952 in Perth, Australia) is a mathematician and polymath known for his work on urban theory, architectural theory, complexity theory, and design philosophy. He has been a close collaborator of the architect and computer software pioneer Christopher Alexander, with whom Salingaros shares a harsh critical analysis of conventional modern architecture. Like Alexander, Salingaros has proposed an alternative theoretical approach to architecture and urbanism that is more adaptive to human needs and aspirations, and that combines rigorous scientific analysis with deep intuitive experience.
Salingaros published substantive research on Algebras, Mathematical Physics, Electromagnetic Fields, and Thermonuclear Fusion before turning his attention to Architecture and Urbanism. Salingaros still teaches mathematics, and is Professor of Mathematics at the University of Texas at San Antonio. He is also on the Architecture faculties of universities in Italy, Mexico, and The Netherlands.
