Joshua Socolar


Professor of Physics

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.
