A complete list of my most relevant publications (in most of the cases, with pdf) is here.
My research interests and work span somewhere in the middle of the following lines:
* Connections between graph theory, time series analysis and dynamical systems: visibility graphs
* Statistical physics: phase transitions, self-organization and self-organized criticality
* Complex networks (theory and applications to networked complex systems)
* Nonequilibrium statistical mechanics: applications to living systems (social and biological self-organization, cooperative behavior, quantitative language).
* Connections between Complex Systems and Number theory
