Joshua Socolar, Professor of Physics and CNCS: Center for nonlinear and complex systems

Joshua Socolar

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
Complex Boolean networks
Genetic regulatory networks
Aperiodic Tilings
