About Me

I am a research fellow at the Centre de Recerca Matemàtica in Bellaterra, Barcelona, Spain. I previously worked as a postdoctoral fellow at the Physics Department at the University of Barcelona, Spain, affiliated to the Complexity Lab Barcelona and to the Universitat de Barcelona Institute of Complex Systems (UBICS). I obtained a PhD in Physics from Université Laval in Québec City, Canada, in 2014 under the supervision of Louis J. Dubé.

Research Interests

Complex systems are composed of many microscopic elements whose interactions lead to emergent macroscopic behaviours. These systems can be of diverse nature: biological (e.g., food webs of ecosystems), technological (e.g., Internet, power grids), or social (e.g., contact/social networks). Examples of emergent properties are the robustness/stability to perturbations of ecosystems, the navigability of the Internet without an explicit knowledge of its global structure, and the susceptibility of a population in regard to large-scale epidemics of emerging infectious diseases.

Understanding the behaviour, or function, of complex systems is achieved through the study of the structure of the interactions between their constituting elements. This in turn is achieved through a network—or graph—paradigm in which the elements are represented by nodes linked together if they interact in the original system. Statistical mechanics, graph theory, geometry and non-linear dynamics then offer a well developed set of concepts and mathematical tools to study and to model the interplay between the structure and the function of complex systems.
