 Research Interests: Theoretical Condensed Matter Physics
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
 Keywords:
Condensed matter • Granular materials • Nonlinear dynamics • Control theory • Genetic regulatory networks • Boolean networks • Tiling theory
