**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
