The International Association of Synaesthetes, Artists, and Scientists (IASAS) advances global awareness of the neurological phenomenon of synaesthesia through support for academic, creative, and community inquiry into cross-modal perception. For ten years, IASAS has cultivated international collaboration among synaesthetes, artists, scientists, educators, and others interested in the study and experience of synaesthesia and multisensory perception. Through interdisciplinary symposia, public lectures, creative exhibitions, online communities, and educational outreach, IASAS serves the public good by fostering curiosity, understanding, and acceptance of synaesthesia as an expression of human neurodiversity. By bridging the arts and sciences, IASAS encourages dialogue across disciplines and cultures, creating space for new research, creative exploration, and shared discovery. As IASAS enters its next decade, the organization continues to expand its global network and support innovative collaborations that deepen public engagement with perception, consciousness, creativity, and the multisensory human experience.
