# Joshua Socolar

## Professor of Physics

### Overview

Prof. Socolar is interested in collective behavior in condensed matter and dynamical systems. His current research interests include:

- Limit-periodic structures, quasicrystals, packing problems, and tiling theory;
- Self-assembly and phases of designed colloidal particles;
- Organization and dynamics of complex networks;
- Topological elasticity of mechanical lattices.
