Soft mechanical instabilities provide a rich framework for generating both form and function. Spanning length scales from the nanoscale to the macroscale, contemporary research is uncovering new ways to harness these phenomena to understand growth and morphogenesis in the natural world, while also enabling the design of next-generation soft robotics, mechanical computing, morphing materials, adaptive locomotion, and reconfigurable architectures. This conference will bring together researchers investigating instability-driven phenomena in fluids, solids, and living matter, with the goal of highlighting how soft mechanics is creating new connections across disciplines. By uniting perspectives from physics, mechanics, applied mathematics, materials science, and biology, the meeting aims not only to showcase recent advances, but also to identify the fundamental open questions shaping the future of soft mechanics.
