Raffaella Sini has a multidisciplinary background in architecture, landscape architecture, planning, and public art. She has advanced degrees in architecture and landscape architecture from the University of Rome La Sapienza. She is assistant professor at the University of Idaho's Landscape Architecture programme, and has taught in several universities and in Asia as assistant professor at the National University of Singapore.

Her design-based research is explicated through the practice of temporary and experimental installations realized with the design collective LAND-I archicolture (2000-ongoing) co-founded with Roberto Capecci and Marco Antonini, and with students and communities in Europe, Asia, and the United States. The use of short-term interventions, for which Raffaella has obtained funding from governments and private foundations, has been instrumental in practicing and teaching process design methodologies in diverse contexts.
