Main research interests

Avalanche dynamics, criticality, acoustic emission, mechanical failure, microseismicity, self-organization, quenched disorder, out-of-equilibrium statistical physics, metastability.


In general terms, my study is focused on  the physical origin and implications of triggering and patio-temporal correlations in mechanical avalanches. I combine the study of conceptual and numerical models with data from acoustic emission (AE) experiments and microseismicity catalogs:

  • Characterization of the spatio-temporal correlations in AE and microseismicity and discussion on the role of heterogeneity.
  • Effect of transient regimes associated to the physical sources of spatio-temporal correlations to the statistics of AE and microseismological data.
  • Identification of mean field behavior and universality classes associated to frictional and  fracture avalanches  under  different driving conditions.
  • Study of self-organized driving towards criticality in granular assemblies from discrete element simulations.

Potential future projects

  • Role of syntering conditions on the scale-free phenomena in AE and seismology.
  • Emerging mechanisms self-organized driving towards criticality.
  • Determination of control parameters to model the branching processes simulating microseismicity and AE.
  • Role of boundary conditions in the separation of scales found in critical systems beyond finite size scaling.

Other interests

Seismology, complex systems, pattern formation, socio- and econo-physics, complex networks.
