The Artificial Nature Transposium (ANT): Transdisciplinary Symposium on Artificial Life and Sustainable Complex Systems connects researchers and industry leaders working with data science and complex systems, specifically in the areas of soft ALife (emergent AI, artificial life modeling), hard ALife (robotics and AI), wet ALife (synthetic biology, biochemistry, disease modeling), sustainability research (ecosystem modeling), and arts & design (music modeling, and computational modeling of material architecture). ANT brings together researchers working within the emerging areas of Artificial Life and Complex Systems, aiming to understand and synthesize life-like systems and apply bio-inspired synthetic methods to other science/engineering disciplines, including AI, Robotics, Computer Modelling, Synthetic Biology, Bio-Materials, and Bio-Architecture, among others. Sustainable development of technologically-mediated complex systems is at the core of ANT, and for this discussion, we bring a transdisciplinary group of innovators, boundary-pushing companies, and creatives in the room. The symposium creates opportunities for experts from diverse fields and sectors to come together to further our understanding of how sciences and technologies of Artificial Nature can advance human–society–nature interactions.
