String Data 2026 marks the next chapter of the international conference series at the forefront of string theory, data science, and machine learning. Hosted for the first time in South Korea in December 2026, the meeting will continue the tradition of bringing together leading researchers across theoretical physics, mathematics, and computer science to explore how modern computational methods and AI-driven approaches can shed light on fundamental questions in high-energy theory and quantum geometry. With a program featuring keynote lectures, invited and contributed talks, panel discussions, and opportunities for collaboration, String Data 2026 aims to further strengthen the interdisciplinary dialogue that has become the hallmark of this series.
