We are interested in understanding the processes through which materials and assemblies shape themselves. As these processes are typically local in nature they often give rise to geometric frustration, prescribing two or more mutually contradicting local tendencies. The cooperative compromises assumed by the material give rise to diverse and complex morphologies and exotic response properties. Implementing these principles in manmade strutures will open new avenues for material fabrication, yet require solving callanging inverse design problems. In addition, we also harbor a long time interest in geometric aspects of chaotic Hamiltonian systems and orientation-dependent handed phenomena.
