"The Ubiquitous Complex Networks"


ABSTRACT


Complex network theory has revolutionized the understanding of complex systems in numerous scientific fields and has offered a deeper understanding on how people, computers or proteins are connected to each other. The intense research on network science has established itself as a new research field with its distinct set of challenges and accomplishments. Many important applications have been developed, such as the design of robust networks or efficient immunization strategies, based mainly on statistical physics approaches. The field is currently extremely active and new interesting challenges arise constantly, with applications in complex social, climate, technological, and biological systems. In this talk I will briefly review the many and surprising results that established the field. I will then focus on the research done in our lab: we are working towards the theoretical understanding of architectural laws in complex systems and we have been able to uncover the self-similar properties of many important networks, a valuable tool to characterize the topology of such networks. Our methods have allowed us to address numerous problems, such as who are the most important spreaders in a community, how functional modules are organized in the brain, or how stem cell types evolve during the embryo growth.
