Currently, I am engaged as a postdoctoral fellow at the Santa Fe Institute.

My research interests are:
  • Statistical Physics 
  • Biological pattern formation
  • Complex Networks (structure, dynamics and evolution)
  • Dynamics of gene regulation
  • Artificial Genomes
  • Self-organized Criticality
  • Genetic Algorithms and evolution of Cellular Automata
