Workshop Goals

Geometrically frustrated assembly is an emerging paradigm for self-organized soft materials, where interactions between self-assembling elements (e.g., particles, macromolecules, proteins) favor local packing motifs that are incompatible with uniform global order in the assembly, either because of shape mismatch between the particles or because of the specificity of the interactions.

This meeting aims at bringing together, for the first time, a panel of theorists and a few experimentalists whose current research covers an aspect of this problem, and thinking together about the key questions regarding the concept and physical models of frustrated self-assembly.

This 3-days workshop is hosted and funded by the Princeton Center for Theoretical Science.
