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;
- Shear jamming and stick-slip behavior in dry granular materials;
- Organization and dynamics of complex networks;
- Topological elasticity of mechanical lattices.

Prof. Socolar is interested in the principles that determine collective behavior in condensed matter and dynamical systems. His current research interests include:
- Organization and function of complex dynamical networks, especially genetic regulatory networks;.
- The spatial distribution of stresses granular materials (e.g. bins of sand, coal, pills, or grain) and jamming phenomena;
- Controlling chaos, or understanding feedback mechanisms that can stabilize otherwise unstable ordered behavior in chaotic dynamical systems;
- Quasicrystals, packing problems, and tiling theory.
- Areas of Interest:
- Theoretical condensed matter physics
Nonlinear dynamics and control theory
Statistical mechanics in nonequilibrium systems
Complex Boolean networks
Genetic regulatory networks
Aperiodic Tilings
