PhD, University of Pennsylvania, Philadelphia, PA, 1987
BA, Haverford College, Haverford, PA, 1980

Research Categories: Theoretical Condensed Matter Physics; Nonlinear Dynamics; Systems Biology

Research Description: 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 biological networks, but also including electronic circuits and social interaction networks;
  • Mechanistic models of genetic regulatory networks;
  • Limit-periodic structures, quasicrystals, packing problems, and tiling theory.
  • Self-assembly of colloidal particles with designed interactions.

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
