Research interests

• Hexagonal Parquet Tilings (PDF).
  This is a paper that was published in the Mathematical Intelligencer. The published article is mistakenly drawn from an earlier draft.
• Boolean networks and gene expression
• Elasticity of granular materials (page under construction)
• Tiling theory
• Controlling nonlinear systems using time-delayed feedback (page not available)
• Self-organization in slowly driven dissipative systems (page not available)
• Quasicrystal stability and elasticity (page not available)
