Fold it, stretch it, build it: biomimicry with Dr. Shu Yang

The article profiles Dr. Shu Yang, a leading materials scientist and biomimicry expert at the University of Pennsylvania, who draws inspiration from nature’s structures to develop innovative, sustainable materials. Her early curiosity about natural phenomena evolved into a career focused on soft matter such as polymers, gels, and composites. Central to her work is biomimicry—studying biological systems like elephant skin, snail mucus, and ocean biominerals to uncover fundamental principles that can be applied to engineering challenges. For example, her team has created carbon-sequestering concrete inspired by the lightweight, porous, and strong structures of marine organisms, aiming to reduce the significant carbon footprint of traditional concrete. Dr. Yang also explores the art of kirigami—cutting and folding materials to alter their mechanical properties and functionality. By strategically introducing cuts, her lab transforms rigid materials into flexible, stretchable forms with applications ranging from building façades that regulate airflow and sunlight to medical devices like breast implant wrappers that optimize support while
