Joshua Socolar, Professor of Physics and CNCS: Center for nonlinear and complex systems
Prof. Socolar is interested in the principles that determine collective behavior in condensed matter and dynamical systems. His current research interests include:
- Limit-periodic structures, quasicrystals, packing problems, and tiling theory.
- Self-assembly of colloidal particles with designed interactions.
- Organization and function of complex dynamical networks, especially biological networks, but also including electronic circuits and social interaction networks;
- Mechanistic models of genetic regulatory networks;

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
