His research, in the last years, focus mainly in the study of complex systems and random networks. More recently has been involved in studies in the following topics:

  • Neuronal networks,
  • Mathematical properties of multiplex networks,
  • Dynamical processes on interconnected networks,
  • Spreading of Diseases in Complex Networks,
  • Explosive percolation.

Other topics of interest are:

  • Granular media,
  • Self-organized criticality,
  • Non-equilibrium phase transitions,
  • Deposition models.
